| 62 | .Sh DESCRIPTION
|
|---|
| 63 | .Nm
|
|---|
| 64 | listens for requests for changes to the Kerberos database and performs
|
|---|
| 65 | these, subject to permissions. When starting, if stdin is a socket it
|
|---|
| 66 | assumes that it has been started by
|
|---|
| 67 | .Xr inetd 8 ,
|
|---|
| 68 | otherwise it behaves as a daemon, forking processes for each new
|
|---|
| 69 | connection. The
|
|---|
| 70 | .Fl Fl debug
|
|---|
| 71 | option causes
|
|---|
| 72 | .Nm
|
|---|
| 73 | to accept exactly one connection, which is useful for debugging.
|
|---|
| 74 | .Pp
|
|---|
| 75 | The
|
|---|
| 76 | .Xr kpasswdd 8
|
|---|
| 77 | daemon is responsible for the Kerberos 5 password changing protocol
|
|---|
| 78 | (used by
|
|---|
| 79 | .Xr kpasswd 1 ) .
|
|---|
| 80 | .Pp
|
|---|
| 81 | This daemon should only be run on the master server, and not on any
|
|---|
| 82 | slaves.
|
|---|
| 83 | .Pp
|
|---|
| 84 | Principals are always allowed to change their own password and list
|
|---|
| 85 | their own principal. Apart from that, doing any operation requires
|
|---|
| 86 | permission explicitly added in the ACL file
|
|---|
| 87 | .Pa /var/heimdal/kadmind.acl .
|
|---|
| 88 | The format of this file is:
|
|---|
| 89 | .Bd -ragged
|
|---|
| 90 | .Va principal
|
|---|
| 91 | .Va rights
|
|---|
| 92 | .Op Va principal-pattern
|
|---|
| 93 | .Ed
|
|---|
| 94 | .Pp
|
|---|
| 95 | Where rights is any (comma separated) combination of:
|
|---|
| 96 | .Bl -bullet -compact
|
|---|
| 97 | .It
|

| 98 | change-password or cpw

|---|

|
|---|
| 111 | .El

|---|
| 112 | .Pp
|
|---|
| 113 | And the optional
|
|---|
| 114 | .Ar principal-pattern
|
|---|
| 115 | restricts the rights to operations on principals that match the
|
|---|
| 116 | glob-style pattern.
|

|
|---|
| 131 | ports to listen to. By default, if run as a daemon, it listens to port
|
|---|
| 132 | 749, but you can add any number of ports with this option. The port
|
|---|
| 133 | string is a whitespace separated list of port specifications, with the
|
|---|
| 134 | special string
|
|---|
| 135 | .Dq +
|
|---|
| 136 | representing the default port.
