160 Lists the matching principals, short prints the result as a table,
161 while long format produces a more verbose output. Which columns to
162 print can be selected with the
164 option. The argument is a comma separated list of column names
165 optionally appended with an equal sign
167 and a column header. Which columns are printed by default differ
168 slightly between short and long output.
170 The default terse output format is similar to
171 .Fl s o Ar principal= ,
172 just printing the names of matched principals.
174 Possible column names include:

206 Modifies certain attributes of a principal. If run without command
207 line options, you will be prompted. With command line options, it will
208 only change the ones specified.

249 Run the password quality check function locally.
250 You can run this on the host that is configured to run the kadmind
251 process to verify that your configuration file is correct.
252 The verification is done locally, if kadmin is run in remote mode,
253 no rpc call is done to the server.

274 Renames a principal. This is normally transparent, but since keys are
275 salted with the principal name, they will have a non-standard salt,

284 Check database for strange configurations on important principals. If
285 no realm is given, the default realm is used.

295 Writes the database in

298 encrypted, the dump will also have encrypted keys, unless
302 is used then the dump will be in MIT format. Otherwise it will be in
