Is it possible to use Active Directory User email address as login credentials in ITCM Explorer ?

Environment

ITCM :14.01 
OS :Windows 2012
DB :SQL
 

Resolution

ITCM doesn't support an email login... only username/password.  You can use only AD credentials or local user account. 
@” is a restricted symbol and cannot be used as part of a username (Microsoft restriction) as it denotes the start of the domain name. If you try and login to Windows with a user name that contains “@” it will fail.Same applies to ITCM explorer.
