Hey Peter, Thx for the reply! I tried the command you suggested and I get error: basic_ldap_auth: WARNING, could not bind to binddn 'Invalid credentials' ERR Success If I remove the "-f sAMAccountName=%s" part of the command you sent then I get the error: basic_ldap_auth.cc(739): pid=23194 :attempting to authenticate user 'uid=brig,“dc=mydomain,dc=com”' ERR Success (I am trying to auth my own userid/passwd so I know it is good and should produce an "OK" and naturally 'mydomain.com' was replaced with my real domain) So adding the -f option does not even allow me to bind. Like I said I am not very familiar with AD yet I would think that the 2nd error at least shows that my bind credentials are working? So I am still stuck yet hopefully these results might help you help me narrow it down? Thx again!
