When OpenID Connect (OIDC) is activated, it's no longer possible to authenticate with LDAP credentials (while it's possible to login with local "Tuleap" credentials). It makes almost impossible for platform that are using LDAP to move to OpenID Connect as existing users will be stuck outside.
LDAP Login should be allowed to ease the transition.
First and foremost, this is made to allow transition from LDAP to OpenID Connect client. The transition can take time but the goal should be to no longer authenticate users against LDAP:
- there should not be more than one source of truth to identify users.
- when tuleap delegate authentication to an OIDC provider, tuleap should no longer manipulate user passwords (even a forward to an LDAP server).
