LDAP Authentification and group membership

[Jean-Francois Gagnon]

Hi!

I'm trying to make this work. My LDAP authentification works ok, but I want it to test if the user is a member of a specific group or not. Well, if I test with any user, it says Successful wheter the user is a member of the group or not. And I want it to failed if the user is not a member of the group. I am using ASDM and test in the AAA Server Groups with the Test button and authentification test

Thanks for your help!

Are we sure that when we run the tests, there's no paremeter that applies for the same users and puts them all in the same group?

Have you tried this with a real user trying to authenticate?

Do you get any useful logs from the server?

What thype of ldap server are you using? Microsoft Windows 2012 or 2008. I got a problem with 2012 not give the groups back with some users.

Same problem as
