user id from LDAP

[reddyy]

Hi,
We are using Cognos 8.2. We want to bring the userid from ldap security to compare it with some table column. How to do this?

Also #sq($account.personalInfo.userName)# is returning userid , fine..
This is present in FM when we point to one environemnt ( Test), but when we point the FM to different env like DEV, the session parameter is not presenting..And when we forcefully try to keep this , it is returning 'blank' value instead of userid
Any clues?
