62.Sh DESCRIPTION
63.Nm
64listens for requests for changes to the Kerberos database and performs
65these, subject to permissions.  When starting, if stdin is a socket it
66assumes that it has been started by
67.Xr inetd 8 ,
68otherwise it behaves as a daemon, forking processes for each new
69connection. The
70.Fl Fl debug
71option causes
72.Nm
73to accept exactly one connection, which is useful for debugging.
74.Pp
75The
76.Xr kpasswdd 8
77daemon is responsible for the Kerberos 5 password changing protocol
78(used by
79.Xr kpasswd 1 ) .
80.Pp
81This daemon should only be run on the master server, and not on any
82slaves.
83.Pp
84Principals are always allowed to change their own password and list
85their own principal.  Apart from that, doing any operation requires
86permission explicitly added in the ACL file
87.Pa /var/heimdal/kadmind.acl .
88The format of this file is:
89.Bd -ragged
90.Va principal
91.Va rights
92.Op Va principal-pattern
93.Ed
94.Pp
95Where rights is any (comma separated) combination of:
96.Bl -bullet -compact
97.It
98change-password or cpw
99.It
100list
101.It
102delete
103.It
104modify
105.It
106add
107.It
108get
109.It
110all
111.El
112.Pp
113And the optional
114.Ar principal-pattern
115restricts the rights to operations on principals that match the
116glob-style pattern.
117.Pp
118Supported options:
119.Bl -tag -width Ds

128.It Fl d , Fl Fl debug

130.It Fl p Ar port , Fl Fl ports= Ns Ar port
131ports to listen to. By default, if run as a daemon, it listens to port
132749, but you can add any number of ports with this option. The port
133string is a whitespace separated list of port specifications, with the
134special string
135.Dq +
136representing the default port.
