First I looked where the message came from
- the message “Undefined attribute type” is reported by the underlying OpenLDAP library: error.c#L60.
- and the meaning of the placeholder is, that it is reported, if an attribute is unknown: LDAP_UNDEFINED_TYPE
It seems that when modifying the attribute “univentionPasswordSelfServiceEmail” and its content, the Schema definition is unknown to OpenLDAP. Please double check that
- the Schema file is present on all servers
/var/lib/univention-ldap/local-schema/self-service-passwordreset.schema
, otherwise reinstall the self-service app - “self-service-passwordreset.schema” is included in
/etc/ldap/slapd.conf
, otherwise typeucr commit /etc/ldap/slapd.conf
and restart the ldap service
