Duplicate Users

Duplicate Users

Hello,
sorry if this is my second post for the same question as I cant find my old question
I've imported users. From AD. But whatever I do, a second user is created whenever I try to login with my userid. (And the password is OK, bizarre)

So I found the below statement in the help docs:
In cases where none of the specified conditions like 'ObjectGUID' , 'loginname+domainname', 'email address','loginname + domain=NULL' are absent in ServiceDesk Plus MSP , a new user will be added.

I want to turn this off and want to login with correct credentials.
Thank you.
