Further to this, we have tried LDAP with DSS v1.23, again with no luck.

(A) We verified general directory/NAS operation by using AD mode to access our AD.

(B) We then tried to use LDAP mode to access to our AD, replicating the directory structure (with People, Groups, and Computers containers under the Base DN) exactly as per DSS User Guide. (tho we note that we created the People & Group OUs, while the existing Computers object was of a "container" type).

We used an LDAP util (Softerra LDAP browser 2.5.3) against the AD to verify correct DN format, and we see regular successful login events in the AD server's Audit Log from the DSS server. BUT no users/groups ever appear in the NAS Resources Users/Groups list.

(C) Back to Netware and LDAP access to eDirectory and DSS v1.32:
We get the following LDAP trace...
"LDAPSearchToCB failed to send any entries, err = remote failure (-635)"
which we understand relates to an invalid/etc. attribute encountered.

If anyone has anything to offer, we would appreciate it!
Regards
