New LDAP Attributes Supported
v1.1.0 adds support for several new LDAP attributes. In order to enable them, make sure they are defined in your LDAP server's schema. Then edit the appropriate provisioner configuration. You must click Save, even if it looks like the attributes you want are already enabled.
eduPersonAffiliation Fix
Prior to v1.1.0, the LDAP Provisioning Plugin incorrectly localized the eduPersonAffiliation value when exporting it. By default, the localized value is the same as the spec value, so most installations are unlikely to be affected by this change. However, if you were relying on the old (incorrect) behavior, you may need to update your integrations.
