CR - TX for your reply, your script & data was very useful. I've made some progress... I still don't know why I can't authenticate using my admin account / password (and NOTHING I do seems to resolve this). BUT - with my improved understanding of the structure of the ldapsearch command (TX SK); and a re-newed attempt to access the ldap server anonymously (CR ;_); it appears that I can now connect to my exchange server.
now, my problem is I still can't run any queries, I only get: # search result search: 2 result: 2 Protocol error After much googling on ldap protocol error 2, I'm again stuck. I found hits that referenced a "-C" option to ldapsearch; which doesn't seem to apply anymore, since I find no doc's on -C in the manpage. I found another hit that might indicate that ldap V3 and exchange 5.5 might produce a protocol error, but I've started using -P2 anyway, with no different response. although this error is returned from the exchange server, the problem has GOT to be with ldapsearch / debian. I CAN do sucessful queries from windows environment. anyone got more ideas? TIA! (again) - Bob
