OpenLDAP and Paging

Hello,
I am using OpenLDAP 2.2.19 on MS Windows Xp. I am having 10000 users and 5000 groups. The problem I am facing is, for an administrator i.e. rootdn configured in slapd.conf, I am able to access all the users and groups with any page size say 1000. But for a normal user, I am getting only 500 entries whatever the the pagesize is. Is there any constraint on amount of data a normal user (not administrator) can retrieve or is there any constraint on Page Control in case of normal user? Also, if I set same user as a rootdn in slapd.conf, I am able to access all the users and groups.
Do I need to make any changes in slapd.conf?
Thanks
Gaurav

Hi,
You need loop through the search till the cookie is returning null from the server's response.
Please find the example code attached below........
int pageSize = Integer.parseInt(PAGESIZE);
PagedResultsControl prc = new PagedResultsControl(pageSize);
ctx.setRequestControls(new Control[] { prc });
int     count=0;
NamingEnumeration searchResults;
byte[] cookie = null;
do {
     searchResults = ctx.search(MY_SEARCHBASE, FILTER, constraints);
     while (searchResults.hasMore()) {
          searchResults.next();
          count++;
     // PagedResultsResponseControl contains the server cookie.
     Control[] responseControls = ctx.getResponseControls();
     for (int i = 0; i < responseControls.length; i++) {
          if (responseControls[i] instanceof PagedResultsResponseControl) {
               // setting new request control from server's response.
               PagedResultsResponseControl prrc =
                    (PagedResultsResponseControl) responseControls;
               cookie = prrc.getCookie();
               if (cookie != null) {
                    prc = new PagedResultsControl(pageSize, cookie, true);
                    ctx.setRequestControls(new Control[] { prc });
} while (cookie != null);
If you have any more queries please revert back to me..........

SAP ECC6 memory and paging issues

Dear Experts
I have recently upgraded my 4.6C systems to an ECC 6 system (DB2 LUW 9.5 on AIX 5.3 TL9 64 Bit OS)
I have been running the LPAR with 14 GB of memory and we are around 100-200+ users using the system, I was monitoring using nmon and found that Physical Memory was around 99.8% Used   (14311.8MB and 22.6MB was free) also the paging space was around 37.2% in result causing the system at times to run slow which can have a very negative effect on the users.
After further investigation I found that after a system restart the Physical Memory would start around 50.9% and increased at a steady pace until it reached 99.8% that is when the system would start using the paging space which would steadily increase, I found that the only solution was a system restart at least once a week to reduce the memory consumption.
At first glance it looked like a database manger memory leak with the process db2sysc, so I searched the net with the search words u201Cdb2 memory leaku201D and found the following APARs and notes.
APAR JR30285 - Pervasive memory leak when compiling SQL statements that use SQL/XML functions
APAR IZ35230 - There is a pervasive unix-specific private memory leak in the security component
Note 1288341 - Memory leak in APPLHEAPSZ -> SQL0954C
Note 1352361 - Memory leak in shared memory area abrfci
Note 1147821 - DB6: Known Errors and available Fixes in DB2 9.5 LUW
After reading the notes and APARs I decided to updated DB2 to the latest fix pack (5SAP), but after the fix pack was implemented it did not solve the memory problem
I started look at different problems with SAP ECC6, db2 and AIX with paging/memory problems and I found the following notes to do with AIX memory and paging but none of them helped as all parameters and settings were set accordingly
789477 - Large extended memory on AIX (64-bit) as of Kernel 6.20
191801 - AIX 64-bit with very large amount of Extended Memory
973227 - AIX Virtual Memory Management: Tuning Recommendations

After even more investigation I found the following evidence suggesting AIX Virtual Memory Manager might have a problem

Problem with OpenLDAP and JNDI

I'm having problem working with OpenLDAP and JNDI.
First I have changed LDAP's slapd.conf file:
suffix          "dc=antipodes,dc=com"
rootdn          cn=Manager,dc=antipodes,dc=com
directory     "C:/Program Files/OpenLDAP/data"
rootpw          secret
schemacheck offthan i used code below, to create root context:
package test;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.NameAlreadyBoundException;
import javax.naming.directory.*;
import java.util.*;
public class MakeRoot {
     final static String ldapServerName = "localhost";
     final static String rootdn = "cn=Manager,dc=antipodes,dc=com";
     final static String rootpass = "secret";
     final static String rootContext = "dc=antipodes,dc=com";
     public static void main( String[] args ) {
               // set up environment to access the server
               Properties env = new Properties();
               env.put( Context.INITIAL_CONTEXT_FACTORY,
                          "com.sun.jndi.ldap.LdapCtxFactory" );
               env.put( Context.PROVIDER_URL, "ldap://" + ldapServerName + "/" );
               env.put( Context.SECURITY_PRINCIPAL, rootdn );
               env.put( Context.SECURITY_CREDENTIALS, rootpass );
               try {
                         // obtain initial directory context using the environment
                         DirContext ctx = new InitialDirContext( env );
                         // now, create the root context, which is just a subcontext
                         // of this initial directory context.
                         ctx.createSubcontext( rootContext );
               } catch ( NameAlreadyBoundException nabe ) {
                         System.err.println( rootContext + " has already been bound!" );
               } catch ( Exception e ) {
                         System.err.println( e );
}this worked fine, I could see that by using "LDAP Browser/Editor".
and then I tried to create group with code:
package test;
import java.util.Hashtable;
import javax.naming.*;
import javax.naming.ldap.*;
import javax.naming.directory.*;
public class MakeGroup
     public static void main (String[] args)
          Hashtable env = new Hashtable();
          String adminName = "cn=Manager,dc=antipodes,dc=com";
          String adminPassword = "secret";
          String ldapURL = "ldap://127.0.0.1:389";
          String groupName = "CN=Evolution,OU=Research,DC=antipodes,DC=com";
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          //set security credentials, note using simple cleartext authentication
          env.put(Context.SECURITY_AUTHENTICATION,"simple");
          env.put(Context.SECURITY_PRINCIPAL,adminName);
          env.put(Context.SECURITY_CREDENTIALS,adminPassword);
          //connect to my domain controller
          env.put(Context.PROVIDER_URL,ldapURL);
          try {
               // Create the initial directory context
               LdapContext ctx = new InitialLdapContext(env,null);
               // Create attributes to be associated with the new group
                    Attributes attrs = new BasicAttributes(true);
               attrs.put("objectClass","group");
               attrs.put("samAccountName","Evolution");
               attrs.put("cn","Evolution");
               attrs.put("description","Evolutionary Theorists");
               //group types from IAds.h
               int ADS_GROUP_TYPE_GLOBAL_GROUP = 0x0002;
               int ADS_GROUP_TYPE_DOMAIN_LOCAL_GROUP = 0x0004;
               int ADS_GROUP_TYPE_LOCAL_GROUP = 0x0004;
               int ADS_GROUP_TYPE_UNIVERSAL_GROUP = 0x0008;
               int ADS_GROUP_TYPE_SECURITY_ENABLED = 0x80000000;
               attrs.put("groupType",Integer.toString(ADS_GROUP_TYPE_UNIVERSAL_GROUP + ADS_GROUP_TYPE_SECURITY_ENABLED));
               // Create the context
               Context result = ctx.createSubcontext(groupName, attrs);
               System.out.println("Created group: " + groupName);
               ctx.close();
          catch (NamingException e) {
               System.err.println("Problem creating group: " + e);
}got the error code: Problem creating group: javax.naming.directory.InvalidAttributeIdentifierException: [LDAP: error code 17 - groupType: attribute type undefined]; remaining name 'CN=Evolution,OU=Research,DC=antipodes,DC=com'
I tried by creating organizational unit "ou=Research" from "LDAP Browser/Editor", and then running the same code -> same error.
also I have tried code for adding users:

}same error.
I haven't done any chages to any schema manually.
I know I'm missing something crucial but have no idea what. I have tried many other code from tutorials from net, but they are all very similar and throwing the same error I showed above.
thanks in advance for help.

I've solved this.
The problem was that all codes were using classes from Microsoft Active Directory, and they are not supported in OpenLDAP (microsoft.schema in OpenLDAP is just for info). Due to this some fields are not the same in equivalent classes ("user" and "person").
so partial code for creating user in root would be:
import java.util.Hashtable;
import javax.naming.ldap.*;
import javax.naming.directory.*;
import javax.naming.*;
import javax.net.ssl.*;
import java.io.*;
public class MakeUser
     public static void main (String[] args)
          Hashtable env = new Hashtable();
          String adminName = "cn=Manager,dc=antipodes,dc=com";
          String adminPassword = "secret";
          String userName = "cn=Albert Einstein,ou=newgroup,dc=antipodes,dc=com";
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          //set security credentials, note using simple cleartext authentication
          env.put(Context.SECURITY_AUTHENTICATION,"simple");
          env.put(Context.SECURITY_PRINCIPAL,adminName);
          env.put(Context.SECURITY_CREDENTIALS,adminPassword);
          //connect to my domain controller
          env.put(Context.PROVIDER_URL, "ldap://127.0.0.1:389");
          try {
               // Create the initial directory context
               LdapContext ctx = new InitialLdapContext(env,null);
               // Create attributes to be associated with the new user
                    Attributes attrs = new BasicAttributes(true);
                              attrs.put("objectClass","user");
               attrs.put("cn","Albert Einstein");
               attrs.put("userPassword","Nale");
               attrs.put("sn","Einstein");
               attrs.put("description","Research Scientist");
               attrs.put("telephoneNumber","999 123 4567");
               // Create the context

}hope this will help anyone.

Database Listing And Paging With Flash Builder

Hello ;
i trying to develop an android application with flash builder.
i have a database and connected it, selected a table and created a service.

Paging over phones and paging horns in CME

Hi all!
Cisco CME provides mechanisms for paging across phones with ephone-dn configurations, and paging across external paging systems that are connected to either FXS or FXO ports via dial-peer configurations. I have done these numerous times.
Recently I've been receiving requests to be able to dial a single paging extension and have the page go out across the phones and the horns/paging controller simultaneously. Has anyone been able to do this, and would you share the info please?
Thanks in advance,
Kevin

Hi,
As per the doc that i shared "InformaCast has no special requirements for how multicast is enabled, and you should use your network vendor’s best practices and design considerations. Multicast is typically routed with Protocol Independent Multicast (PIM) that is deployed in either sparse or dense mode. InformaCast will work with either mode.
For WAN links where your circuit provider will not route your multicast, you can configure GRE tunnels, which carry your multicast traffic from the location where the InformaCast server is located to its recipients. The only traffic that needs to traverse these GRE tunnels is the multicast traffic you might want to route. The tunnels do not need to create a full mesh between sites; they only need to be configured from the hub location to the spoke location(s). Please see the following link for details:
http://www.cisco.com/en/US/tech/tk828/technologies_configuration_example09186a00801a5aa2.shtml
For recipients to receive the audio portion of InformaCast broadcasts, they make requests using Internet Group Management Protocol (IGMP). While most networks default to IGMPv2, newer recipients may use IGMPv3. If newer recipients are being deployed, be sure to enable the newer protocol version on network devices."

LCDS Caching and Paging

How do we keep items in the LCDS data services cache independent between user sessions? If I use session in the destination, I can still update an item in one users cache and have it change another users item (if the identity attribute is the same).
Another way to look at this question is that we want to use the data management services to enable dynamic loading and paging of large sets of data. We don't want to utilize it for data management between sessions.
Thanks.

Have you seen the part of the example configs where it talks
about what is required for data paging to work?

It seems to imply to me that you need the paged fill methods
in your config in addition to the regular ones.
I admit I have not got as far as getting a working paging
setup yet, although this is something I will need to get working in
the near future.

Jdbc and paging

Hi,
i have the following doubts regarding the jdbc and paging please clarify me...
1)Is it advisable to use stored procedure to implement paging is records
are more in database
2)If the records are more in the database and we execute
select * from table where id >10 and id<15 then will
the query execution will be slow because the database is large(and so stored procedure will be faster)
or as we are selecting only records between 10 and 15 so the
query execution is not slow
3)will the recordset help in solving the probem
4)is there a way to select the count of the records along with the records for display in the page
the count of the records is required to display the next button
if two queries are to be written one to display the next button and second to get the records to
display on the page then the system may be slow when many users are accessing and using stored
procedures may be better
5)when we write the select query with 'for update' clause then the row will be locked
or the table is locked .
6)when we write the select query with 'for update' clause then until we execute the update
query the lock will be there and the lock will be released on executing the update query
is that right then what about the case if after the select query we get some exception
and code does not reach the update query then what about the lock will be lock remain
and give problem
regards
Javid

1) that would really depend on you goals. for performance only, stored procedures are precompiled so should be faster.
2) definitely you should only select what you want and limiting the number of rows you return will speed up your query.
3) what do you mean by that? a recordset represents the collection of rows returned from the query so should help you.
4) it depends on your database. for instance, MySQL has a function to return the number of rows returned. however, some database has an unbuffered mode so that the first few rows will be returned very quickly without knowing how many rows are there, in which case, you won't know the number of rows until all the rows have been retrieved.
5 and 6 are database-dependent, while most rdbms only lock the selected rows by default, some lock the entire table.

Jabber for Windows openLDAP and Deskphone Control

Hello all
I have a new install of 9.1 CUCM, with CUCM IM and Presence. I'm trying to get Jabber 4 windows functioning with an openLDAP directory, and also get Deskphone control working. I suspect i missed something with the configuration as this 9.1 interface is a little different than i'm used to.
First of all, does the concept of a Jabber-Config.xml still apply to a 9.1 install or does the "Service Profile Configuration" in the CUCM interface write the Jabber-config.xml file for you? If my customer uses openLDAP for their LDAP how should I configure the "Service Profile" or do I still use a jabber-config.xml file?
I have successfully tied openLDAP into CUCM with Authetication and brought the users into CUCM. I tested Authentication by logging into the End user page for both CUCM and the CUP server so I know authenticaiton is working. I can login to Jabber but when i click on Help "connection Status" it shows me only connected to "PRESENCE" and "OUTLOOK ADDRESS BOOK" my "Directory", and DESKPHONE" will not connect.
Can I actually get a copy of "my jabber-config.xml" file from the CUCM server to see what it looks like?
Thanks all

Ok I have half of the problem resolved. I got Deskphone controll working with CTI.
Still working on the LDAP issue with openLDAP
My config file looks like so
<?xml version="1.0" encoding="utf-8"?>
   EDI
   1
   ldap.acme.ca
   389
   backup.acme.ca
   389
   0
   uid=voipldap,ou=Users,dc=acme,dc=ca
   password
   givenname
   (&(objectClass=inetOrgPerson)
   telephonenumber
   uid
   ou=users,dc=acme,dc=ca
I got this from page 117 of this guide
http://www.cisco.com/en/US/docs/voice_ip_comm/jabber/Windows/9_1/JABW_BK_CA48EE46_00_cisco-jabber-for-windows-administration.pdf
The error I'm getting "invalid credential" but i know they are good because i'm using the same account and path for the CUCM LDAP sync.
Any help would be appreciated.

OpenLDAP and multiple users sharing same account

Hello.
I have been running an OpenLDAP directory for a while now and users' homes live on an NFS share, which causes problems when the same user is logged in to multiple computers at the same time.
I can tell which users are logged in to which computers and then disable the accounts that are used more than once.
Is there a way to disallow multiple logins or automatically log users out when they log in to different machines? I have 600+ users.

Hi
You need 2 accounts.

Physical memory and paging

I know in SAP's world, memory means physical memory + paging. I want to know which program has contribution for swap.
Suppose there is 4G physical memory on an application server, em/initial_size_MB = 4G, abap/heap_area_nondia = 4G.
1) If there is no dialog processor running and one background job running which claims 2G memory, I want to know will swap occur?
2) If there is one dialog processor running which claims 2G memory and one background job running which claims 2G memory, will swap occur?

By ST03N you can check the workload, by OS06 the swap .
By transaction ST02 you can check the folllowing parameters:
SAP Roll area parameters
- ztta/roll_first          : First amount of roll area used in a dialog WP
- ztta/roll_area             : size of the local SAP Roll area in the work process
rdisp/ROLL_SHM      : size of SAP roll Buffer
rdisp/ROLL_MAXFS     : size of entire shared SAP roll area
SAP Extended Memory main parameters :
em/initial_size_MB : size of SAP extended memory allocated when                         the SAP instance starts up
em/blocksize_KB : size block which split SAP Extended Memory
ztta/roll_extension : maximum size of a user context in the SAP Extended memory
SAP Heap Memory main parameters :
abap/heap_area_dia       : quotas oh SAP heap memory that a dialog                                 process can allocated.
abap/heap_area_nondia : quotas oh SAP heap memory that a nondialog                    process can allocated.
abap/heap_area_total     : size that can be allocated in total by all work                    process.
abap/heaplimit           : Workprocess restart limit of heap memory
if helpful reward point is appreciated

OpenLDAP and WLSP9 LDAPRealm

How do I configure my OpenLDAP so that WLSP9 LDAPRealm will actually
authenticate the users. I have the realm debugging turned on , and I
can
see that the user has been found, but no matter what password I use
the authentication fails. I know that the LDAPRealm tries to bind to
my
LDAP server with that username and password, but currently I only have
the
rootdn and rootpw set in my server , no other access control . Should
I include
access control lists in my slapd.conf file ???
Thanks in advance.

I'm fairly new to OpenLDAP myself but I think I had the same issue as you. I
certainly had to add a few ACLs to my slapd.conf and one looks like what you
are after. Add it to the bottom of slapd.conf:
access to attr=userPassword
by anonymous auth
by * none

OpenLDAP and Octet String.

Hi all, I had a new problem with my jsp's applications that must connect to a openLDAP server.
I resolve the connection and the search problems, as I said in other post.
Now the problem is that I must use the connection for authenticate the simple user.
I discovery that I can do that using the dn parameter.
The problem is that if I would do it I should do too much connections because I must do:
1)connect with the admin user;
2) search the dn value of the user that is trying to connect using the username's value that I receive withe login's form;
3) close the connection;
4) and finnally reconnect to the ldap server with thenew credentials!
I don't like this solution so I'm here because I would know if there are some thing to do for take the value of a octet string on a ldap server.
The alternative is "traslate" the string with the password write on my login's form in the same format of userPassword's field.
I know that the octet string is a byte's array and I try to cast my string in a bye's array and compare with the other with the method contains() but it retunes false.
I find this topic:
http://forums.sun.com/thread.jspa?threadID=721595&messageID=4162046
but there are two problems:
1) as I said I don't know how get the value of a octet string's field;
2) the code of for's cycle five me a compilers' error and I never seen a for's cycle withe the string so I don't know how I can traslate it in a classic for's cycle...
Some one can help me?
Thanks inadvance.

First I use the contaims() method.
Second i insert as value to control the string casts in byte's array with the method getBytes().
Than it returns true!

How To Ask Questions The Smart Way

Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.
