.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
|
|
If built with krb4 support, it implements both the Heimdal Kerberos 5
|
|
administrative protocol and the Kerberos 4 protocol. Password changes
|
|
via the Kerberos 4 protocol are also performed by
|
|
.Nm kadmind ,
|
|
but 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
|
|

|
|
.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.

ports to listen to. By default, if run as a daemon, it listens to ports
|
|
749, and 751 (if Kerberos 4 support is built and enabled), 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 set of ports.
|
|
.It Fl -no-kerberos4
|
|
make
|
|
.Nm
|

ignore Kerberos 4 kadmin requests.
