Since werk #13501, only LDAP connections are processed, the user has the user attribute for.

In older versions of Checkmk only one LDAP connection was supported, setting the user attribute "connector" to "ldap". This attribute was later changed from "ldap" to "default", leading to failed logins now, because no LDAP connection matches.

The problem will be fixed with this werk. A workaround was, to manually change the user attribute of affected users from 'connector':'ldap' to 'connector':'default' in ~/var/check_mk/web/USERNAME/cached_profile.mk.
