ID: 13508 Title: Fix failed logins for LDAP user created with Checkmk versions below 1.4 Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 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/USERNAME/cached_profile.mk.
