Re: sometimes login issue using ldap users

Dear Saleh,

Would it be possible to use some network packet sniffing tool like tcpdump / wireshark to see what happens with the LDAP request from OMERO.server and the reply from your institutional LDAP for both the failed/hung and the successful logins?

Of course, such network traffic capture may contain all manner of confidential data so we would be fine if you could just summarize what you see. It would be good to be able to pin down if the problem is that OMERO somehow fails to properly make the request or fails to act on the response or what. Ideal would be if you could capture the Blitz log for those periods of packet capture.

(Readers from the OME team can see previous logs in QA 17749, 17751.)

Cheers,
Mark

Hi Mark & all,

i traced it with wire shark it seem that socekt timeout issue, because after Ack- Ack connection after a while a request from omero to my ldap not replied by my ldap because the ldap has the connection drop it.
all what i said is a Believe

and now when this situation happen, i am trying to do
bin/omero login
but the terminal is hanged
actually i gave up because i tried many thing and i tested everything :( , if it is possible someone to check my server remote will be thanks.
i believe that the problem in some where in OMERO server
cheers
Saleh

Dear Saleh,

Have you been able to inspect the captured wireshark traffic data well enough to tell if there is some suspicious difference between the LDAP requests from OMERO that your institutional server does reply to and those that it doesn't? If there is some clear indication that OMERO is doing something wrong then that might help us to pinpoint the issue. I am not aware of any of our other LDAP users (including ourselves at Dundee!) running into this issue but maybe there is something in those failed LDAP requests that could be a smoking gun? (If anyone else is monitoring this forum thread because they see a similar issue elsewhere then please speak up.)

It might also be checking with your institutional IT if they have any way to set up a test that their LDAP server even receives the failed requests from OMERO and, if so, if it logs any problem with them that explains the lack of response back to OMERO. Given the exact times and IP they may be able to easily dig up some clues for us.

Cheers,
Mark

Hi Saleh,

See:

You can try adjusting the timeout.

This is the Global Catalogue that you are connecting to, right? Was the error the same before? How many return values are you expecting? How long does the query take with ldapsearch?

Cheers,
~Josh.

Hi Josh,
thx for your support
first of all, this new logs are from new test fresh server, it has the same issue similar to our main server
actually i did
what in past you wrote in this link viewtopic.php?f=4&t=7376
i added
Code: Select all
-Dcom.sun.jndi.ldap.connect.pool.timeout=3


after i overwrite ldap.pool.timeout i not getting any Socekt close Error message any more but the issue still reproducible
do suggest to change timeout to another value or what ?
and when this issue occur i can log in for local users(omero native users )

is there any additional timeout key for ldpa, which can also configured
cheers
Saleh

Dear Saleh,

Have you tried scripting a bunch of ldapsearch queries to see if you can use that to reproduce the same issue from the machine hosting the OMERO server? How do those queries go?

Cheers,
Mark
