Hi you all, is it possible to synchronise a db users table with active dire

You should be able to write a process to verify if the user is in sync to the database. LDAP sync (to the bset of my knowledge) only gives you the number of users added or updated and not the user account itself. So you to check if this number is >0 and write a procedure to query the user and verify against the database.
As a general best practice, this may be okay for small user count but as the user count increases, this may be an overhead. So make sure you design this with due consideration on performance

Thanks sathya, but from my personal experience about LDAP (in general and not for Appian) with the LDAP command I can get only the information about the people and group that are on an OU.
We used LDAP Sync for syncronizing the Appian user with an LDAP Domain Group and its works well. But if I'm not able to use this node to syncronizing another db user that aren't in appian.
My question is: Is it possible to do this?

I dont think you can use the LDAP sync plug-in to do the synching to another database. What I was suggesting was - once the user is successfully imported into Appian, you can loop through the users and for each user, query the user attributes using the user() function and write this info out to your database. This way, Appian acts as an intermediary. The other option is to build your own LDAP plug-in to do the job.

Thanks for your suggestion..
