Hello Shannan,
A good practice is to put the password as case sensitive in CMOD (option in the settings of the CMOD Instance in the CMOD Admin client).
Because most of the time LDAP needs to keep lower/upper case password, which could break the authentication with LDAP.
CMOD by default store everything in uppercase, and then do a insensitive comparison. And ADMIN is the only user that don't use LDAP, it bypass it (it is hard coded in CMOD).
With CMOD 9.0, you define other users (there is a limit on how many users, but don't remember yet) that bypass LDAP, in case you have some LDAP problems, and need to administer CMOD.
Sincerely yours,
Alessandro
