### Retrieving a List of Principals

To generate a listing of principals, use the `kadmin` `list_principals` command, which requires the "list" privilege. The syntax is:

         list_principals [expression]

where expression is a shell-style glob expression that can contain the characters `*`, `?`, `[`, and `]`. All policy names matching the expression are displayed. The `list_principals` command has the aliases `listprincs`, `get_principals`, and `getprincs`. For example:

         kadmin: listprincs test*
         test3@ATHENA.MIT.EDU
         test2@ATHENA.MIT.EDU
         test1@ATHENA.MIT.EDU
         testuser@ATHENA.MIT.EDU
         kadmin:

If no expression is provided, all principals are printed.
