Hi I have working integrated ADS and Samba environment where ADS is used to authenticate all the Windows users. I now want to use the ldapmodify utility to query the ADS, but I obviously need to use a mode which requires strict binding. I created a specific user in ADS for this access. However, when I use DIGEST-MD5, I get an "Invalid credentials (49)" error. (All of the modes produce errors). To validate the test, I used LDP.EXE, running on the ADS node itself, and selected "DIGEST" for the bind operation. It also failed with the same error. I would appreciate any pointers as to whats required to bind. Thanks in advance Mark de Lange
