 Username mapping

 usernames. Again, only use this setting if the server guarantees the
 uniqueness of this attribute.
 
+Groups mapping
+^^^^^^^^^^^^^^
+
+Specifying the `groups-claim` setting in the OpenID configuration enables group
+mapping functionality. The data provided in the `groups-claim` should be
+a list of strings that correspond to groups that a user should be a member of in
+{pve}. Any groups reported by the OpenID provider that do not exist in {pve} are
+ignored.
+
+By default, groups are appended to the user's existing groups. It may be 
+desirable to overwrite any groups that the user is already a member in {pve}
+with those from the OpenID provider. Enabling the `groups-overwrite` setting
+removes all groups from the user in {pve} before adding the groups reported by
+the OpenID provider.
+
+In some cases, OpenID servers may send groups claims which include invalid
+characters for {pve} group IDs. By default, each invalid character is replaced
+with an underscore (`'_'`). To adjust the character used for replacement, adjust 
+the `groups-replace-character` setting to any valid character for a {pve} group
+ID (i.e. includes alphanumeric characters and any of the following: `'-'`,
+`'_'`, `'.'`).
