userchfn [<target>] [<user>] [-c <file>] [-f <full name>] [-r <room number>] [-w <work phone>] [-h <home phone>] [-o <other>]
With the userchfn utility you can modify the account of an user on cluster of passwdd hosts. The client connects with each server specified in passwdc.conf and sends a request for modification of the user's gecos field. Note, that each user can modify her own gecos data, with the only exception of the other field that can be modified only by an administrator.
The first argument of the command is the login name of the user whose account you want to modify. If omitted, the account of the currently logged user is subject of modification. You may want to send the request not as the user who is currently logged on. In such case you should explicitly specify a user name as the second argument of the userchfn command.
userchfn recognizes these options:
Use the file specifed as a parameter of the option to configure the daemon.
The full name of the user.
The room number of the user.
The work phone of the user.
The home phone of the user.
The miscellaneous gecos field of the new user. Only an administrator has the rights to change this value.
Configuration data for the userchfn utility. For more information see the passwdc.conf(5) manpage.
If not-null the full pathname for an alternate configuration file. Overridden by the -c option.
There should be some. If you found one or more of them send a mail and I will do my best to fix them.
