[keycloak-user] Having trouble with LDAP attribute mapping in 1.3.1

Thanks for the info. Now I think I know what's going on.
The issue is that currently when we import users from LDAP (federation
in general), we sync the configured attributes to the Keycloak DB. But
during searching, we don't sync the attributes from LDAP to Keycloak DB
anymore. So I guess you did the steps like this:
- You first authenticate as LDAP user "joe" (or search this user from
admin console), which imported this user into Keycloak DB
- Then you created mapper for the 'applications' attribute. But user
'joe' was already imported into Keycloak DB from the previous step, right?
I believe that when you import some other user from LDAP, which is not
yet exist in Keycloak DB, the 'applications' attribute will be there.
For the existing user, the only possibility right now is to use
"Synchronize all users" or "Synchronize changed users" on LDAP
federation screen. This will update existing users into Keycloak DB as
well, so 'joe' will be updated.
Please let me know if it helps. Looks that it's something we should
address better in Keycloak.
