<err> cb.auth.ldap_authorization - Error Loading LDAP configuration file ... raise KeyError(key) KeyError: 'ldap_user_org'
In the ldap.conf file, this line for ldap_user_org was commented out:
# (OpenLDAP, FreeIPA only) Specify what org your users belong to # ldap_user_org = ou=Users
Whether using OpenLDAP or only AD authentication, the settings for the option not being used should be kept in the ldap.conf file but left blank.
