Hi: I have ciscoSecureACS 2.4 for NT authenticating dial-in users against the NT user database. Now I have a few users who don't have accounts in the NT domain but need access to the network and need to be authenticate when they dial in. I could create local accounts for them either on NAS or in ACS. But they have accounts in an email application called "IMail" which creates DS entires to each user account in its built in LDAP server. So my thinking is since CiscoSecure ACS supports LDAP based authentication, why can't I use it for these users? My questions are can I do that while authenticating some users via NT user database and some users locally and some users via LDAP? Has anybody got this to work with IPswitche's IMail LDAP server? Thanks for any help.
