Add Kerberos-LDAP support
Created by: impleri
Hi,
I've been hitting a problem with integrating GitLab to my company's LDAP service. I've tracked it down to LDAP not providing a mail, email, or userPrincipalName field. However, our LDAP does provide krb5PrincipalName which provides an internal company email address. When I tack that field name to gitlab-omniauth-ldap's strategies, everything works.
