From admin I went to administration > security > users, this is how users are appearing:
Admin user:
Administrator (in bold)
admin (under administrator)
Other users:
John Doe (in bold)
john-doe1234 (under John Doe) john.doe@domain.com (under john-doe1234)
LDAP_default: john.doe (under john.doe@domain.com)
This is the username. Since it’s not john.doe exactly, the issue won’t be mapped. Username and e-mail addresses are considered possible SCM accounts by default.
However, you can add john.doe as an SCM account by updating the details of the user.
