[keycloak-user] LDAP with Kerberos, login with different user

[Marek Posolda]

Ah, Ok. So it's about admin users. Also note that in latest 1.4 version 
we will have new "impersonation" feature, which allows admin to 
temporarily login on behalf of any other user. Isn't this even better 
for your usecase?
