Modify user information
Modify user information, by using the user modify command. Typically, modifications are made to keys and secrets, email addresses, display names, and access levels.
To modify information about a user, you must specify the user ID
(--uid=_USERNAME_) and the attributes you want to modify.
Example
[root@host01 ~]# radosgw-admin user modify --uid=janedoe --display-name="Jane E. Doe"
To modify subuser values, specify subuser modify and the subuser ID.
Example
[root@host01 ~]# radosgw-admin subuser modify --subuser=janedoe:swift --access=full
