.Sh DESCRIPTION
The
.Nm
program is used to make modifications to the Kerberos database, either remotely via the
.Xr kadmind 8
daemon, or locally (with the
.Fl l
option).
.Pp
Supported options:
.Bl -tag -width Ds
.It Xo
.Fl p Ar string ,
.Fl -principal= Ns Ar string
.Xc
principal to authenticate as
.It Xo
.Fl K Ar string ,
.Fl -keytab= Ns Ar string
.Xc
keytab for authentication principal
.It Xo
.Fl c Ar file ,
.Fl -config-file= Ns Ar file
.Xc
location of config file
.It Xo
.Fl k Ar file ,
.Fl -key-file= Ns Ar file
.Xc
location of master key file
.It Xo
.Fl r Ar realm ,
.Fl -realm= Ns Ar realm
.Xc
realm to use
.It Xo
.Fl a Ar host ,
.Fl -admin-server= Ns Ar host
.Xc
server to contact
.It Xo
.Fl s Ar port number ,
.Fl -server-port= Ns Ar port number
.Xc

.It Xo
.Fl l ,
.Fl -local

If no
.Ar command
is given on the command line,

will prompt for commands to process. Some of the commands which take a
principal as argument
.Ns ( Nm delete ,
.Nm ext_keytab ,
.Nm get ,
.Nm modify ,
and
.Nm passwd )
will accept a glob style wildcard, and perform the operation on all
matching principals.  Commands include:
.\" not using a list here, since groff apparently gets confused
.\" with nested Xo/Xc
.Bd -ragged -offset indent
.Nm add
.Op Fl r | Fl -random-key
.Op Fl -random-password
.Oo Fl p Ar string \*(Ba Xo
.Fl -password= Ns Ar string

.Op Fl -key= Ns Ar string
.Op Fl -max-ticket-life= Ns Ar lifetime
.Op Fl -max-renewable-life= Ns Ar lifetime
.Op Fl -attributes= Ns Ar attributes
.Op Fl -expiration-time= Ns Ar time
.Op Fl -pw-expiration-time= Ns Ar time
.Ar principal...
.Pp
.Bd -ragged -offset indent
Adds a new principal to the database. The options not passed on the
command line will be promped for.
.Ed
.Pp
.Nm delete
.Ar principal...
.Pp
.Bd -ragged -offset indent
Removes a principal.
.Ed
.Pp
.Nm del_enctype
.Ar principal enctypes...
.Pp
.Bd -ragged -offset indent
Removes some enctypes from a principal. This can be useful the service
belonging to the principal is known to not handle certain enctypes.
.Ed
.Pp
.Nm ext_keytab
.Oo Fl k Ar string \*(Ba Xo
.Fl -keytab= Ns Ar string
.Xc
.Oc
.Ar principal...
.Pp
.Bd -ragged -offset indent
Creates a keytab with the keys of the specified principals.
.Ed
.Pp
.Nm get
.Op Fl l | Fl -long
.Op Fl s | Fl -short
.Op Fl t | Fl -terse
.Ar principal...
.Pp
.Bd -ragged -offset indent
Lists the matching principals, long format gives more information, and
terse just prints the names.
.Ed
.Pp
.Nm modify
.Oo Fl a Ar attributes \*(Ba Xo
.Fl -attributes= Ns Ar attributes
.Xc
.Oc
.Op Fl -max-ticket-life= Ns Ar lifetime
.Op Fl -max-renewable-life= Ns Ar lifetime
.Op Fl -expiration-time= Ns Ar time
.Op Fl -pw-expiration-time= Ns Ar time
.Op Fl -kvno= Ns Ar number
.Ar principal...
.Pp
.Bd -ragged -offset indent
Modifies certain attributes of a principal. If run without command
line options, you will be prompted. With command line options, it will
only change the ones specified.
.Ed
.Pp
.Nm passwd
.Op Fl r | Fl -random-key
.Op Fl -random-password
.Oo Fl p Ar string \*(Ba Xo
.Fl -password= Ns Ar string
.Xc
.Oc
.Op Fl -key= Ns Ar string
.Ar principal...
.Pp
.Bd -ragged -offset indent
Changes the password of an existing principal.
.Ed
.Pp
.Nm password-quality
.Ar principal
.Ar password
.Pp
.Bd -ragged -offset indent
Run the password quality check function locally.
You can run this on the host that is configured to run the kadmind
process to verify that your configuration file is correct.
The verification is done locally, if kadmin is is run in remote mode,
no rpc call is done to the server.
.Ed
.Pp
.Nm privileges
.Pp
.Bd -ragged -offset indent
Lists the operations you are allowed to perform. These include
.Li add , 
.Li change-password ,
.Li delete ,
.Li get ,
.Li list ,
and
.Li modify .
.Ed
.Pp
.Nm rename
.Ar from to
.Pp
.Bd -ragged -offset indent
Renames a principal. This is normally transparent, but since keys are
salted with the principal name, they will have a non-standard salt,
and clients which are unable to cope with this will fail. Kerberos 4
suffers from this.

When running in local mode, the following commands can also be used:
.Bd -ragged -offset indent
.Nm dump
.Op Fl d | Fl -decrypt
.Op Ar dump-file
.Pp
.Bd -ragged -offset indent
Writes the database in
.Dq human readable
form to the specified file, or standard out. If the database is
encrypted, the dump will also have encrypted keys, unless 
.Fl -decrypt
is used.

.Op Fl -realm-max-ticket-life= Ns Ar string
.Op Fl -realm-max-renewable-life= Ns Ar string
.Ar realm
.Pp
.Bd -ragged -offset indent

possible to have more than one realm served by one server.
.Ed
.Pp
.Nm load
.Ar file
.Pp
.Bd -ragged -offset indent
Reads a previously dumped database, and re-creates that database from
