NAME

vauthenticate - Authenticate a virtual user

SYNOPSIS

vauthenticate

DESCRIPTION

vauthenticate reads a domain name, user name, and pass phrase from standard input, and authenticates the virtual user. If authentication is successful, it prints out information about the virtual user on stdout

The domain name, user name, and pass phrase are passed to vauthenticate on standard input each seperated by a NUL byte.

The output consists of a series of lines containing an identifier, an equal sign, and the data for that identifier, terminated by a newline. The identifiers are:

UID: The base user's numerical user ID.
GID: The base user's numerical group ID.
USER: The base user's name.
HOME: The base user's home directory.
MAILDIR: The virtual user's mailbox directory, relative to "HOME".
VUSER: The virtual user's name.

OPTIONS

None

RETURN VALUE

Returns 0 if authentication succeeds, and non-zero otherwise.

CAVEATS

Although the output from vauthenticate appears to be suitable for using as shell input, care must be taken to escape characters that would cause the shell to misbehave, such as semicolons.

RESTRICTIONS

This program will not authenticate non-virtual users.
