I have configured the Active Directory and groups in external database and everything works good. I am able to login to Analytics using the Name in the ldap server i.e. Tom Bank, but I want to be able to login with the id t_bank instead (t_bank being id for his email firstname.lastname@example.org). I am not sure where I need to make this change.
For external database, I had to put Tom Bank in the membername instead of t_bank else it would not work.
Thanks SVSS. Yes this worked. The only difference being that I wanted to use the id in the email and not the complete email address. The doc that you shared showed how to login using the entire email address.
So instead of 'Mail', 'sAMAccountName' needs to be used so as to be able to login with only the id i.e. s_ty instead of email@example.com.
