Solim..
FYI the username is case sensitive.. so make sue that when you create an account in the DLP console that points to an AD account that they match cases. You cannot login on the DLP console unless someone has created a local account in the DLP console. Accounts are NOT connected to AD, it ONLY uses Ad for authenitcation purposes.
Also in the DLP UI, there is a setting that can disable the account as well.. so you will need to login to the console either as Administrator or as another user that can control User access.
As far as logging into the Console there is an "Administrator" Account that is local to the system. This username IS CASE sensitive as well so make sure you use the CAPITAL "A" in Administrator
If you do not knwo the password for the Administrator Account, you will need to open a case with SYMC to get it retrieved.
Good Luck,
Ronak
