popauth -- manipulate POP authorization DB
SYNOPSIS
popauth [ -trace tracefile ] [ -debug ] [ -init [ -safe ] ]
[ -list [ user | ALL ] ] [ -delete user ]
[ -user user [ password ] ] [ -help ] [ -version ]
DESCRIPTION
The popauth program allows POP subscribers to add or change the secret values used to generate their authentica-
tion credentials, or to verify the existance of their records.
In addition, the super-user or master POP user can add, delete, or reset credential data for a user, or list
which records exist. Only the super-user may initialize the database. popauth is useful only when the APOP (or
SCRAM) configuration option is defined. See the INSTALL file in the Qpopper distribution for more information.
Under normal usage, popauth prompts for a new secret, just like the passwd program. It then updates the autho-
rization DB.
With the -user switch, the super-user or master POP user can create or reset credential data for the specified
user. This switch allows the password to be specified on the command line, which avoids the usual prompts and
checks. This is mostly useful in a batch environment, such as in a script.
With the -init switch, the super-user can create a new (or zero the existing) authorization DB.
With the -list switch, the super-user or master POP user can verify the presence of a record for the indicated
user, or list users who have records. Users can verify the presence of their own records with this switch.
With the -delete switch, the super-user or master POP user can remove a user entry from the authorization DB.
