Directory Proxy Sever

Greetings,
I have been able to set up the directory proxy server in our test environments, but was a little concerned about the performance tuning parameters. Currently everything is default. I have searched the net to see if there are any available benchmarks or performance tuning criteria and have not found anything suitable. For example:
a) "Maximum BER Size" the default value is set "no limit". I searched for the definition of BERSIZE and found this out (http://docs.sun.com/app/docs/doc/819-0986/nsslapd-berbufsize-5dsconf?l=en&a=view). Still not sure whether to leave it default or play around with it. Our ldap servers in production enterprise level with over 200k to 300k searches a day.
b) "Client Connections" The value can be between 2^1 or 2^6. I was just not sure whether to adjust with experience or if there is a benchmark somewhere.
Any documentation links or comments would be welcome.
Thanks
Ahsan

Thanks for the reply. I tried look for the idsktune binary and could not find it on the on the system. After researching I found a blurb that stated Java ES, Native Package Distribution (6.3) does not include the binary. However if it the zip distribution is installed then it is provided. Is there a place I can download it?
ThanksI got idsktune with dsee7 zip, and it does come with v6 dsrk zip too I believe. Its not a panacea of knowledge or anything but its nice to have. It will tell you if you do not have enough open files set which is important. You can run ulimit -a to check number of open files on your system. 1024 is too low for a DPS. I dont recall the default on a rhel 5.5 system. I have mine at 8192 which can be much higher if you prefer. I added the 2 lines below to my limits.conf file to make setting permanent, or you can set with ulimit on the fly.
/etc/security/limits.conf
* soft nofile 8192
* hard nofile 65536

Solaris Name Service Cache and Directory Proxy Problem

We have some Solaris 10 clients ldapcliented to a Directory Proxy Server. After 15 minutes, the Solaris name service cache will fail to communicate to the proxy instance and the proxy instance's readconnectionsrefused attribute will start incrementing.
At first it seemed we would need to increase the worker-threads and num-bind-limit, but those do not fix the problem.
At the same time the name-service-cache starts failing, I am still able to query and search the proxy. I have set up a Jmeter test which continues to run and they never fail.
It seems very consistent that the problem with the name-service-cache occurs every 15 minutes and I am able to reproduce this at the client's site and in my lab. Restarting either the proxy or the name-service-cache clears the problem.
Has anyone else seen this problem?

The idle-timeout on DSEE was set to none, which I believe is the default. I tried setting it to 1200 and 2400 seconds without success.

Problem in installing Directory Proxy server

Hi all! Recently downloaded the trial version of sun one directory proxy server. After installing the sun one DS 5.2 . I tried to install sun one proxy server..when it asks for configuration server information i have given the admin id and password ....
but it gave me following error message
"The given Administrator Id/password combination was not accepted by the
Configuration Directory Server.
The Sun ONE configuration directory administrator is the ID typically used to
log in to the console."
I did used the same id and password to login to console & i am able to log in.
Please advice.

Two quick hints.
First off, instead of hitting <Enter> to accept the default for the username [admin], type "admin" (without the quotes) as if you were giving different credentials. There's a known issue during the installation where the default text doesn't work.
Additionally, I had to change my admin password in the configuration directory to cleartext in order to get it to work. For some reason the password encryption during the bind was never successful. To do that:
dn: uid=admin,ou=Administrators,ou=TopologyManagement,o=NetscapeRoot
changetype: modify
replace: userPassword
userPassword: {CLEAR}password
I have no idea if this addresses the problem itself or just a symptom, but it did allow me to install DPS. You might want to give it a shot.

Proxy Sever !!

Hello !!
Can anybody please let me know as to how should i make my java
program compliant with proxy sever (in other words ...what changes are required in a java program so that it becomes compatible with a proxy server)....what i want to do is....i want to transfer/copy mails from any mail server into my hard-drive through java program(i am using JavaMail API).
I am able to fetch mail from an Intranet's mail server(which requires authentication)but when i try to do that for any other email provider which gives free pop3 service ,while working under a proxy server(for example runbox.com,hotpop.com,softhome.net etc.) ........an UnknownHostException is thrown(connection failed).
Thank you.

Does directory proxy server 6.0 support access to ds5.1SP3

Hi,
Does anyone have experience with setting up a directory proxy server 6.0 as a frontend to directory server 5.1SP3 servers ?
(where can I find a list of supported directory servers by the proxy ?)
I would like to use the proxy as part of the migration to a new data centre.
Thanks

Yes Directory Proxy Server 6.0 works with DS 5.1SP3.
DPS uses LDAPv3 protocol and works with most of the LDAPv3 compliant servers. It has been tested with Sun DS, Active Directory, OpenLDAP and OpenDS.
Some specific feature may require the support of the Proxied Authorization Control (RFC 3829), but that's it.
Regards,
Ludovic.

Directory Proxy not accepting connections

Hi,
We are having issues with our Directory Proxy servers 6.3. We recently moved an application that makes a lot of searches to the proxy and we started getting the error below. This causes all bind to fail when we start getting this error. Does anybody have this issue or idea what could be causing it?

Installing Sunone Directory Proxy server

Hi all! I am in the process of installing sunone directory proxy server. also in the same machine i have directory server and administration server.
For some reason directory poxy installation fails at the end.
look at the log file all i can see is
Admin Server refused to disclose its pid!
can any one had this experience or share some thoughts.
Thanks

Root is running Sun One Directory Proxy Question ?

While i was installing the directory proxy server, i gave all root to own the files? Is Sun One Directory Proxy suppose to run as root or can i run as non-root user ?

You can (and probably should) run as a non-root user, assuming you're running on a port above 1024.
If you've already installed as root, and root owns all the files, the following should theoretically work:
- Shut down DPS
- Edit <dps-root>/etc/dpsDefaultConfiguration.ldif, and change the ids-proxy-con-userid attribute to the user ID you would like the server to run as
- Modify the same entry in the directory server that holds your proxy's configuration information, like:
ldapmodify -h config_dir_host -p config_dir_port -D "cn=directory manager" -w password
dn: ids-proxy-con-config-name=<instanceName>,ou=system,ou=dar-config,o=NetscapeRoot
changetype: modify
replace: ids-proxy-con-userid
ids-proxy-con-userid: <same value as you put in the LDIF file above>
- Change the ownership of all the files in the DPS install directory
- Change over to the user that you selected and try to start the DPS process

When i click on mozilla firefox i get a pop up that says proxy sever refusing to connect and i have been usinf mozilla firefox for the past two years

proxy sever will not connect

Is a proxy server required to access the internet at your location? Many businesses require the use of a proxy server but if your at home you shouldn't need a proxy.
To disable the use of a proxy sever click on the Firefox Button (or tools menu) then click options. Click on the advanced tab --> Click on the Network tab --> Under Connection click Settings --> Then click on circular button next to use System Proxy Settings. Hit OK then OK again to exit the options dialog.

ODSEE 11g - DPS Directory proxy server suddenly increase load average

Hi all
Recently upgraded from directory server 5.2 to ODSEE 11g, one directory proxy configure to one master directory server and one consumer directory server.
all the three instances are in the same sparc t3 machine.
Directory proxy server alerts server load average on the machine is above 6.00 normally it is 0.66. I'm not sure what is causing the sudden burst in the load ? the traffic is normal there is no abnormal requests coming to the server. proxy performance degrades over the span of 24 hours ....and Once i restart the proxy services (dpsadm restart) all load averages comes to normal and directory proxy runs normal for the next two - three weeks. The same cycle continues ...I'm not sure what was causing the sudden load increase.
I increased the JVM heap size from 1GB to 2 GB still continue to have the problem ..did anyone else experience similar problem. How did you fix it....
Any input or advise in the right direction is much appreciated.
Thank you.

server load I'm referring to "prstat command" - server load average suddenly shoot up from 0.66 to 6.00 ie) the CPU usage. Alert is from our server monitoring tool not related to directory proxy.
Clients report connections time out (etime goes from etime=0 ..2..4.....) over 24 hours i can see the etime increases and eventually the proxy server get hung and non responsive. Once I restart all the performance back to normal at-least for another two weeks.
I suspect there might be a memory leak or JVM Garbage collection issue -- any expert input how to figure this out will help.
Here is the JVM args in the proxy server "Xms2g -Xmx2g -Xmn1g -XX:SurvivorRatio=4 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC"
Here is a jstat during the problem

Sun One Directory Proxy unable to start error DPS.pid file was not found

We finally able to install Sun One Directory Proxy 5.2 , but we are unable to start the Proxy server, we are getting error "Since the DPS.pid file was not found, DPS-server is assumed down
Anybody has any clue / ideas that we would very help fulll?
Thank

I've been struggling with this and another problem with DPS for a couple of weeks.
It generally starts up fine when you dont have SSL enabled. The moment you enable SSL, a couple of things go for a toss:
1. The problem mentioned above surfaces. Are you facing this problem even without SSL?
2. If you log into the Administration console, and try to make changes to the DPS configuration, it will give an error stating that "Error in writing to Configuration Directory". But apparently, it will manage to save things. Just that when you try to start it with SSL enabled, it won't. Neither from the command line, nor the GUI.
Anyone managed to fix this? Sun informed us that there is a problem with Jars, but thats about it.

Question on Sun Directory Proxy Server 5.2.4

Hello Guys,
Is it a good idea to have DPS and DS on the same server? Did anyone run into any issues? We have four Sun DS servers four-way master replicated on Windows 2003 std. We are in the process of evaluating Sun Directory Proxy server to resolve single point of failure between our custom apps and LDAP servers. I would appreciate any insights on Sun DPS implementation on Windows 2003 Std.
Thanks

While it might not be too good an idea (you essentially want the DPS for load balancing AND failover, right? So why risk putting it on the same machine ;) ), it does work.
I recently implemented DPS on Solaris, and things generally work fine. (The command line interface isn't too reliable though). If you are thinking of routing all your traffic over SSL (ie, Client---ssl--->DPS---ssl--->DS), make sure you apply the latest patch available for the DPS. The dps524.jar that comes with the default installer isn't what it used to be (JES 2005Q4), and will give you issues when configuring SSL for DPS. Apart from that, things are more or less a breeze.

What IP load balancers in front of Directory Proxy Server?

In the highly available topology design, two Directory Proxy Servers sit behind IP load balancers. What IP load balancers are folks using for this?
We happen to have F5 load balancers, but I was a bit disappointed to learn that these proxy the connections, and so the initial LDAP client IP address is swollowed up by the F5. This seems to rob a lot of usefulness in Directory Proxy / Directory Server, not to mention make the DP / DS logs less helpful. Anyway around this?
Thanks,
Amos

Hello,
Many customers use F5.
However, there is no mechanims at the LDAP protocol level to carry initial client IP address down to the ultimate server

Tuning directory proxy server parameters

I need help to tune following parameters of Directory proxy server 5.2patch4.
simultaneous operations per connection
Total operations per connection
Simultaneous connections to this group
simultaneous connections per ip address.
Before tuning these parameters, I wanted to know how can I find current usage of above parameters from directory server/directory proxy server. Right now there is no value set for these parameters.
Is there any tool/command line utility or any other way to find current usage of these parameters?
Any help will be appreciated. Thanks in advance.
Thanks
-Ashok

I think the default is unlimited. You can use these
params to tune your server.Thanks for response.
How do I know the baseline to set these parameters? What tool/utility can I use on Proxy server/Directory server in order to find the baseline for these parameters.
To make it more clear, how can I find from proxy server/DS server that how many currently simultaneous operations per connection are going on..
how many total operations per connection are running..
how many simultaneous connections to this group are running.
how may simutaneous connections per ip address are running.
Please let me know if you need further info.
Thanks again.

Issue with binary attribute types through Directory Proxy Server 6.3.1

I'm having problems with DPS 6.3.1.1 on Solaris 10 with binary attribute types. From most LDAP servers, requesting an attribute such as userCertificate would return userCertificate;binary without any issues. However, DPS seems to consider these two separate attributes. In order to see userCertificate;binary, I have to ask for it in that exact format. This obviously is causing trouble for many clients as they shouldn't care about the binary type as it's the same attribute.
I've tried to correct this with a virtual data transformation (dpconf add-virtual-transformation 'PKI Tree' read add-attr-value userCertificate \${userCertificate\;binary}) but the end results are the same. Any ideas on how I can correct this one?
Thanks in advance.
