.. note::
If a user's ID Attribute changes, a new Mattermost account is created that is not associated with the previous account. If you need to change this field after users have signed-in, use the :ref:`mmctl ldap idmigrate <administration-guide/manage/mmctl-command-line-tool:mmctl ldap idmigrate>` command.

.. note::
The ID attribute value is matched verbatim - Mattermost applies no case normalization. With PostgreSQL's default case-sensitive collation, a change in casing is treated as a new user and a separate account is created. Ensure your AD/LDAP server returns this attribute with consistent casing.

.. note::
This attribute is only used when AD/LDAP Group Sync is enabled and it is **required**. See the :doc:`AD/LDAP Group Sync documentation </administration-guide/onboard/ad-ldap-groups-synchronization>` for more information.

.. note::
The Group ID attribute value is matched verbatim - Mattermost applies no case normalization. With PostgreSQL's default case-sensitive collation, a change in casing means Mattermost no longer recognizes the previously synced group and treats it as a new, unlinked group. Ensure your AD/LDAP server returns this attribute with consistent casing.
