Change authentication source?

Hi!

I have recently added LDAP authentication to an installation with a bunch of users, and AD users can authenticate via LDAP.

Now, in the user management menu it is possible to switch authentication sources from local to LDAP. How is this supposed to work? When I change a user’s backend from local to LDAP, she cannot login anymore with neither her local nor LDAP password.

Hi,

sorry for the stupid question. I have tried to find a sort of HOW TO implement LDAP authentication. Do you have something to start with?
TIA,
F
