55.Sh DESCRIPTION
56The
57.Nm
58program is used to make modifications to the Kerberos database, either remotely via the
59.Xr kadmind 8
60daemon, or locally (with the
61.Fl l
62option).
63.Pp
64Supported options:
65.Bl -tag -width Ds

89one or more principals as argument
90.Ns ( Nm delete ,
91.Nm ext_keytab ,
92.Nm get ,
93.Nm modify ,
94and
95.Nm passwd )
96will accept a glob style wildcard, and perform the operation on all
97matching principals.

157.Ar principal...
158.Bd -ragged -offset indent
159Lists the matching principals, short prints the result as a table,
160while long format produces a more verbose output. Which columns to
161print can be selected with the

241.Ed
242.Pp
243.Nm password-quality
244.Ar principal
245.Ar password
246.Bd -ragged -offset indent
247Run the password quality check function locally.
248You can run this on the host that is configured to run the kadmind
249process to verify that your configuration file is correct.
250The verification is done locally, if kadmin is run in remote mode,
251no rpc call is done to the server.
252.Ed
253.Pp
254.Nm privileges
255.Bd -ragged -offset indent
256Lists the operations you are allowed to perform. These include
257.Li add ,

259.Li change-password ,
260.Li delete ,

265.Li modify .
266.Ed
267.Pp
268.Nm rename
269.Ar from to
270.Bd -ragged -offset indent
271Renames a principal. This is normally transparent, but since keys are
272salted with the principal name, they will have a non-standard salt,
273and clients which are unable to cope with this will fail. Kerberos 4
274suffers from this.
275.Ed
276.Pp
277.Nm check
278.Op Ar realm
279.Pp
280.Bd -ragged -offset indent
281Check database for strange configurations on important principals. If
282no realm is given, the default realm is used.
283.Ed
284.Pp
285When running in local mode, the following commands can also be used:
286.Pp
287.Nm dump
288.Op Fl d | Fl Fl decrypt
289.Op Ar dump-file
290.Bd -ragged -offset indent
291Writes the database in
292.Dq human readable
293form to the specified file, or standard out. If the database is
294encrypted, the dump will also have encrypted keys, unless
295.Fl Fl decrypt
296is used.
297.Ed
298.Pp
299.Nm init
300.Op Fl Fl realm-max-ticket-life= Ns Ar string
301.Op Fl Fl realm-max-renewable-life= Ns Ar string
302.Ar realm
303.Bd -ragged -offset indent
304Initializes the Kerberos database with entries for a new realm. It's
305possible to have more than one realm served by one server.
306.Ed
307.Pp
308.Nm load
309.Ar file
310.Bd -ragged -offset indent
311Reads a previously dumped database, and re-creates that database from

315.Nm merge
316.Ar file
317.Bd -ragged -offset indent
