.Sh DESCRIPTION
.Nm
listens for requests for changes to the Kerberos database and performs
these, subject to permissions.  When starting, if stdin is a socket it
assumes that it has been started by
.Xr inetd 8 ,
otherwise it behaves as a daemon, forking processes for each new
connection. The
.Fl -debug
option causes
.Nm
to accept exactly one connection, which is useful for debugging.
.Pp
The
.Xr kpasswdd 8
daemon is responsible for the Kerberos 5 password changing protocol
(used by
.Xr kpasswd 1 )
.
.Pp
This daemon should only be run on the master server, and not on any
slaves.
.Pp
Principals are always allowed to change their own password and list
their own principal.  Apart from that, doing any operation requires
permission explicitly added in the ACL file
.Pa /var/heimdal/kadmind.acl .
The format of this file is:
.Bd -ragged
.Va principal
.Va rights
.Op Va principal-pattern
.Ed
.Pp
Where rights is any (comma separated) combination of:
.Bl -bullet -compact
.It
change-password or cpw
.It
list
.It
delete
.It
modify
.It
add
.It
get
.It
all
.El
.Pp
And the optional
.Ar principal-pattern
restricts the rights to operations on principals that match the
glob-style pattern.
.Pp

.Bl -tag -width Ds

.It Xo
.Fl p Ar port ,
.Fl -ports= Ns Ar port
.Xc
ports to listen to. By default, if run as a daemon, it listens to port
749, but you can add any number of ports with this option. The port
string is a whitespace separated list of port specifications, with the
special string
.Dq +
representing the default port.

.Sh EXAMPLES
This will cause
.Nm
to listen to port 4711 in addition to any
compiled in defaults:
.Pp
.D1 Nm Fl -ports Ns Li "=\*[q]+ 4711\*[q] &"

This acl file will grant Joe all rights, and allow Mallory to view and
add host principals.
