> We have a postgres sql in backend with all the user informations. > Can we connect to the postgressql for authentication? or How can we achieve this? The Gluu Server can only connect to a backend LDAP or Active Directory server for authentication... SQL databases are not supported. > How can we able to access to other applications once we logged in? Once the user has an active session in the Gluu Server, they should be able to navigate to all other applications using Gluu for authentication without having to re-authenticate. It may be helpful for you to [schedule a meeting](http://gluu.org/booking) with us so we can walk through your requirements together.

You need to synchronize LDAP with your Postgress database. This can be accomplished with a simple cron job, or you can use commercial tools like Radiant Logic. Another strategy you might want to consider is to perform a one-time import from the DB-->LDAP. And then make sure when use information is changed, you call the Gluu Server SCIM endpoint with the updated information. As William suggested, you may want to schedule a meeting.

Hi Jake, I'm going to close this ticket out for now. Feel free to re-open if needed, or open a more specific ticket regarding issues youre facing that we can reproduce and help you troubleshoot. Thanks, Will
