Integrating BIP with multiple LDAP servers

Hi,
my question is very simple. In Admin->Security Configuration->Security Model section i've setted Security model combobox with LDAP value. Then i've filled all LDAP information field (for example:URL). All works. But in my rpd i 've multiple LDAP servers (multiple URL) and in the form i can insert information about only one LDAP server.
Is it possible configure BIP with multiple LDAP servers?
Thanks
Giancarlo
P.S. I'm using OBIEE 10g

Run Admin Server with multiple Managed Servers each using different userid?

We currently run separate WebLogic domain instances for each business application in a Unix environment. Each one is created using a unix userid unique to that application and which owns all the files and is used to run the process when that particular WebLogic instance is started up. We have run this way for a while.
I am considering altering our approach to the one that is recommended, i.e. in our Production environment we would run a single Admin instance with numerous managed servers. One issue I'm stuck on is the fact that in our current environment, each application has a different unix userid that owns the files making up the WebLogic domain instance and that WebLogic instance is run under that userid.
I've investigated and experimented using WebLogic 10.3 preview and WebLogic 10.0, but I haven't been able to determine what I have to do to make each managed server's files and processes belong to a different unix userid, if that is even possible.
Is there a way, using the recommended approach, where there is a single Admin instance that has multiple managed servers whose files and processes are owned by different unique, unix userids?
If not, how would you separate access to each of the Managed Servers so that the programmers who maintain them don't have access to Managed Servers that they are not responsible for?
Thanks for any help or suggestions.....

Hi:
I played with this stuff and I found that this will work, without the Location elements:
<IfModule mod_weblogic.c>
MatchExpression /app1 WebLogicHost=server1|WebLogicPort=7003
MatchExpression /app2 WebLogicHost=server2|WebLogicPort=7003
</IfModule>
Also this will work too, with no entries inside the IfModule element:
<Location /app1 >
SetHandler weblogic-handler
WebLogicHost server1
WebLogicPort 7003
</Location>
<Location /app2 >
SetHandler weblogic-handler
WebLogicHost server2
WebLogicPort 7003
</Location>

Application Server slowdown with multiple proxy servers ?

Our environment has our iAS boxes talking to iWS web servers which are front-ended with iPlanet Proxy servers (Proxy 3.53 I believe). We are seeing significant slowdown if we try and hit our web apps through the proxy as opposed to going directly to the web server (bypassing the proxy servers). One of our "proxy" guys recalls hearing that there is an issue with the app server's handling of sessions if requests from the same user come in to the web server (and by extension the app server) from multiple proxy servers with different ip's. Has any body ever encountered this or does any body know if the app server has an issue handling the same sessions whose requests come from different ip addresses (different proxies)?

The proxy work with HTTP 1.0 and the webserver with HTTP 1.1.
This difference could be the cause of your problems.

Multiple LDAP Servers in Fusion Middleware (OBIEE 11g)

Hello,
I have a question, regarding integration of multiple LDAP servers with single Weblogic Server of Fusion Middleware (OBIEE 11g). We are currently using OBIEE 10g. We are on verge of migrating to 11g. However, I have a question regarding the LDAP server.
Our two applications run on two distinct LDAP servers. The plan is to provide a single sign on link for OBIEE 11g reports to the end users and depending on what application they are using, they must be authenticated against the respective LDAP server.
So, my question, is it possible to Integrate two different LDAP servers in the Weblogic of Fusion Middleware (OBIEE 11g). If so, what would be the steps. Any helpful document will also be appreciated.
Thank you,
Chandu.

Yes, you can configure multiple authentication providers one by one as you generally do.
When you configure multiple Authentication providers, use the JAAS Control Flag for each provider to control how the Authentication providers are used in the login sequence. You can set the JAAS Control Flag in the WebLogic Administration Console.
REQUIRED—The Authentication provider is always called, and the user must always pass its authentication test. If authentication succeeds or fails, authentication still continues down the list of providers.
REQUISITE—The user is required to pass the authentication test of the Authentication provider. If the user passes the authentication test of this Authentication provider, subsequent providers are executed but can fail (except for Authentication providers with the JAAS Control Flag set to REQUIRED).
SUFFICIENT—The user is not required to pass the authentication test of the Authentication provider. If authentication succeeds, no subsequent Authentication providers are executed. If authentication fails, authentication continues down the list of providers.
OPTIONAL—The user is allowed to pass or fail the authentication test of this Authentication provider. However, if all Authentication providers configured in a security realm have the JAAS Control Flag set to OPTIONAL, the user must pass the authentication test of one of the configured providers.

Cisco ACS 5.2 authentication against multiple LDAP servers

Hi Folks,
I have a wireless network that uses ACS 5.2 to handle authentication. The ACS is integrated with an Active Directory LDAP server (my_ldap) and is working correctly at the moment. The authentication flow looks like this:
- User tries to associate to WLAN
- Authentication request is sent to ACS
- Service selection rule chooses an access-policy (wireless_access_policy)
- wireless_access_policy is configured to use my_ldap as identity source.
A sister company is about to move into our offices, and will need access to the same WLAN. Users in the sister company are members of a separate AD domain (sister_company_ldap). I would like to modify the wireless_access_policy so that when it receives an authentication request it will query both my_ldap and sister_company_ldap, and return a passed authentication if either attempt is successful. Is this possible?

Assuming you're already authenticating using your AD binding and AD1 as your identity source, you can add a further LDAP server as another identity source and add this to your identity store sequence in your access policy to authenticate against both.
You can also add multiple LDAP servers and add them both to the identity store sequence (if you're not using AD1).

How to configure one TREX host with multiple index servers ?

Hi All,
Does anyone know how to configure TREX on the one host,
with multiple index servers ?
Reason for this is to make better use of resources available on the host server(4 Gig, 4 Processor, Windows2003), to improve the search performance of
our KM content for portal users.
I am using TREX 7 and have not been able to do this,
despite reading the Single and Distributed install
documentation.
Any help would be appreciated.
Regards,
Andres

Hi Andres,
To make use of the RAM a Server provides you have to run two indexserver processes (each can then consume 2 GB);
Proceed like this:
1. Go to TREXdeamon.ini; check if section [indexserver2] is there (it is already provided, but not active in standard installation)
2. In TREXdeamon.ini go to
[daemon]
references sections below
programs=nameserver,preprocessor1,indexserver1,queueserver,alertserver
and add indexserver2 here. Restart TREX; second porcess is then started; can be checked in TREX monitor in Portal as well
3. To distribute existing indexes to the new process, start TREXadmintool and go to Index: Landscape
Go to the last two columns and move the indexes (move master here/secondary mouse click)
If you don't distribute the indexes the new index server process will be regarded when an new index is created.
Hope this helps!
cheers
Bettina

Multiple LDAP servers on single System

hi,
Would like to know if its a good idea to have multiple LDAP servers running on a single System (Hardware) ..
100,000 user base
We would like to run the old and new LDAP databases on the same server till we phase out the old LDAP database after migrating all applications..
System:
2 x V880 4CPU 8GB RAM --multi-master configuration
4 x V420R 4CPU 8GB RAM -- read only replicas

Shouldnt be an issue - thats not a particularly large user base and thats some heft y HW. Keep in mind though that they will be on different ports so any software you migrate may eventually need tweaking to the default port when the new takes over.

LDAP Authentication Scheme - Multiple LDAP Servers?

How to set up ldap authentication so that multiple ldap servers are available? Scenario: ldap service is replicated through several servers, but does not sit behind a common dns/reverse proxy connection, so applications would list each ldap server and attempt to contact each in order if one or more ldap servers is unreachable.

Multiple LDAP Servers and Attribute-Based Data Partitioning

Hello
We currently want to implement following szenario on Netweaver 2004s. From the
following SAP Help documentation we want attribute based data partitioning:
http://help.sap.com/saphelp_nw70/helpdata/EN/4e/4d0d40c04af72ee10000000a1550b0/frameset.htm
The difference to the SAP document is that we want a distribution of attributes over
multiple LDAP servers. So we tried to fit that concept into xml. see attached xml source.
The Portal finds both LDAP Systems but it is NOT that the useres are beeing merged
but they appear as two distict users in the portal UME. If you do a lookup in the portal
usernamagent system you get and see two users.
User1: unique ID = USER.Datasource1.uid
User2: unique ID = USER.Datasource2.uid
Obviously the UME system was not able to merge that information of the two distict
LDAP Systems. MSADS and Lotus Notes.
Hence my questions:
1) is it possible to distribute attributes over multiple ldap data sources
2) any ideas why UME constructs two different users based in Datasource ID's specified in XML
Thanks for any contributions or ideas,
Ulrich Scherb

Hi Ulrich,
Hope your problem is resolved. We are using EP7 and SP18. We are doing some study on your first issue. i.e. Distributing a user attribute into multiple LDAPs. Can you please let me know the feasibility? If yes, what are all step do I have to follow? Expecting your valuable answer. Thanks in advance!

BSPs configuration with multiple apps servers

Hi Masters,
This is regrarding configure ICM and BSPs on our production box with multiple application servers.
We have our production box in a cluster environment.
The central instance is dbciSAP and apps servers are sapaps2 thru sapaps6. The database is on shared disks. Whenever the central instance fails sapaps2 takes the control and become as dbciSAP but the main dbciSAP never become a application server when ever sapaps2 acts as dbciSAP. Since we have configured load balancing concept in production environment the users can login to system thru any application server. This is waht our environment.
As part of our production box to SAP 4.7 upgrade from 4.6C, we are asked to configure the environment to deploy BSPs. We have successfully configured and deployed the BSPs in our DEV and QAS system (Both are central instances with no application servers) except production box which is due in the next month.
The process we follow to activate BSPs is as follows:
1.Define an ICM service port in /etc/services file.
2.Add the ICM related parameters in instance profiles.
3.Make sure the ICM status is active in SMICM tx.
4.Activate the BSP services in SICF as per OSS note 571484.
Now, the question is how to configure the same ICM service and activate the BSPs since we have multiple multiple application servers.
Subsequently What I am enquirying is:
Do I need to define ICM service ports on each and every hosts where the application servers are running?
Do I need to make changes to each and every instance profile of the application server?
What are the differences in configuring ICM services on central instance and application instances?
Appreciate any help in this regard.
Thanks and Regards
Murty Patchipala

Grasshopper,
I think what you should really read up on is the SAP WebDispatcher. If are serious about running BSP/ICM across multiple app servers, this is the key technology:
http://help.sap.com/saphelp_nw04/helpdata/en/42/5cfd3b0e59774ee10000000a114084/frameset.htm This may also answer some of your questions about profile parameters.
Other than that I can share what we did. We did activate the ICM and services on all app servers and central instance. The service ports of the individual servers aren't that important now because of the WebDispatcher (at least they aren't visible to the user).
Yes we did make some of the ICM profile changes in each instance profile. If your settings are the same, consider using the default profile. Are their particular settings you are interested? I will look over ours, but I don't remember any huge differences from APP server to Central Instance.

Session cleanup issue with multiple Application servers

Hi ,
I am facing a strange problem with multiple application servers. The java Webdynro session does not get cleaned up completely when user closes the browser ( without using logoff ). On re-login it gets handle of old session and then fails for consecutive view on other webdynpro iviews with an invalid session error. It again starts working with a refresh event.
Any ideas/suggestion if you have seen something similar before ?
Thanks and regards,
Amit.

Hi Amit
It seems that issues is not server related, but caused by your client browser. I know, for example, that IE8.0 keeps user session even if two separate browser instances opened on the same client machine. IE 7.0 and lower behave differently - they are separate user sessions per browser instance.

Issue listeneing queue from Weblogic Cluster server with multiple managed server

Haveing issue listeneing queue from Weblogic Cluster server with multiple managed server.
Weblogic Cluster structure is like
Weblogic Cluster01
--ManagedServer01(http://server01.myhost.com:7001)
--ManagedServer02(http://server02.myhost.com:7001)
JMS Servers
JMSserver01 targeting: ManagedServer01
JMSserver02 targeting: ManagedServer02
JMSmodule
ConnectionFactory01 targeting:JMSserver01,JMSserver02
UDQueue01 targeting:JMSserver01,JMSserver02
Uniform Distributed Queue in Monitoring tab showing like this
mysystemmodule!JMSserver01@UDQueue01
mysystemmodule!JMSserver02@UDQueue01
So when I am sending message to any Host(by specifying the provider URL) its distributing equally on both server like
mysystemmodule!JMSserver01@UDQueue01 10
mysystemmodule!JMSserver02@UDQueue01 10
But when try to listen message from these queue, it is listening from one server, for which URL given to connect.
mysystemmodule!JMSserver01@UDQueue01 0
mysystemmodule!JMSserver02@UDQueue01 10
untill I connect to other server by giveing its URL, will not able to access other message left on the queue.
Solutions that tried
1) we have tried give both server URL coma sparated in provider URL
we need to configur same scenario for 5 managed server with 3 listener on other servers.
Do any one have solution for this.

You need to have:
1. Consumers connected to each UDQ member
OR
2. If no consumers in some of the members is expected, you can configure Forward Delay (specify the amount of time, in seconds, that a queue member with messages, but with no consumers, will wait before forwarding its messages to other queue members that do have consumers):
http://docs.oracle.com/cd/E12839_01/apirefs.1111/e13952/taskhelp/jms_modules/distributed_queues/ConfigureUDQGeneral.html
For example you can set it to 10 (10s)

How to control one server with multiple clients via TCP/IP

I am wanting to control a single server with multiple clients. Only one client would be active at a time, so there would be no conflict. I want to use TCP/IP. So far, I have programmed a cluster that passes data back to the server with no problems. The challenge come in when a second client is added to the mix. I have't been able to figure out how to turn each client on and send the appropriate data and then turn it off so it doesn't keep sending the same data to the server.
Here are the things that I have considered and did some preliminary testing, but don't really know how to impliment:
1. Send a numeric on the front of the cluster packet that tells the server that data is on the way.
2. Send a boolean on the front of the cluster packet to somehow turn the server TCP/IP on.
The problem I have found is that LabVIEW TCP/IP doesn't like to be turned on and off. If it doesn't get the data it expects, it goes into a reset mode and that kills the response time.
Any help?

You should consider implementing a set of simple one-byte commands that can be sent back and forth between the Server and the Clients. You can base all of these ideas off the example in the Example Finder under Networking >> TCP and UDP called Multiple Connections - Server.
You will have two loops in the server VI: one to wait for new connections, and one to send and receive data from the existing connections. For instance, after one of the clients connects, it can request control of the server to send data to it by sending the character "R" for request. Every time the send/receive loop of the Server executes, the first thing it can do is to check all the existing connections to see if any of the clients have sent a control request ("R"). If so, it will create a buffer (array) of control requests. This could be in the form of Connection IDs or indexes in the array for a particular Connection ID. Your choice.
After the Server receives a request for contol, if it is not already under control by another client, then it can send a response to the first client on the control request list. For instance, the server could send the first client a "S" command for send. Note that after the clients send their control request, they should execute a TCP Read and wait indefinitely for the server to respond with the one-byte "S" command. Then, once the client in control is finished sending data to the server, it could send the character "X" telling the Server to release it from control.
The example I mentioned above already does a similar thing. Note how when a client wants to disconnect, they send the letter "Q". You can see this in the Multiple Connections - Client VI. The Server then checks each individual connection to see if it's received this one-byte command, and if it has, it closes the connection to the client. This is what you would want to implement, but instead of having just one command, you'll have to distinguish between a few and build up a buffer of control requests.
Finally, if a client does decide to disconnect in your application, they could send the command "Q" just like the example above. At this point, close the connection and remove that Connection ID from the array of connections. You will also have to handle the case that this client was in the request control waiting line when it disconnected, in which case you need to delete it from that array as well.
This will definitely work for you, but it will take some work. Best of luck!

Populateing Calendar Server with calendar events???

Hi all, is it possible to populate a user's calendar in Calendar Server with particular events? We are building a communications environment that will initially be comprised of Comms Express and Messaging server and later Calendar Server. This is for a student communications (ie email and possibly later calendar) system.
I'm interested in knowing whether a user's calendar can be populated with predefined events. In our case, that would be to populate a student's calendar with the student's exam timetable?
Thanks in advance,
Stewart

=> add the events directly into the users calendar using WCAP and the calmaster account to 'proxyauth' into the account.
=> create a calendar and invite the users to the 'event'
=> import the events from an .ics file from the command line.
=> create a resource and get the users to subscribe to the resource - the user can then create a calendar group which combines all the subscribed groups with their own personal calendar.
Each option has it's own strengths/weaknesses such as how to update the events if things change, how to administer/access/edit the 'source' of the calendar data for non-administrators, how the events 'appear' to the user, whether you want to allow the user to delete the event, whether the event needs/should alert the user when it occurs (alarms) and so on. You would be best trying all four and seeing which matches your requirements the closest.
