[ActiveDir] AD access "strong authentication required"

[Olivier Marie]

Hello everybody   I would add an entry in my AD (win 2003) from a server RedHat/Apache/PHP.   I was connecting with ldap_connect, using admin user login and password. Everything was ok but some patches and reboot was done by another person, and now It doesn't work :   - When I connect with admin user login and password, I obtain "strong authentication required". - but I can always connect from php to AD using anonymous connection (works great)   Admin user login and password have not been modified. We are newbie on AD and we're not ruling win2003 administration… Could you give us an idea to go further in ours investigations ?   Many thanks Olivier
