Thread:Extension talk:LDAP Authentication/AutoAuth with Windows AD : cannot pull preferences/reply (3)

Final word on this ... aside from the $wgLDAPSearchStrings that was preventing the proxy bind, the other main issue was the encryption setting; in our particular setup, binding will only work if $wgLDAPEncryptionType is left unset.

Now all is well, login and pulling preferences from AD work as expected.

Cheers,
