The qpopauth program allows POP subscribers to add or change the secret
values used to generate their authentication 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. qpopauth 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,
qpopauth prompts for a new secret,
just like the passwd program. It then updates the authorization DB.
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.
the super-user can create a new (or zero the existing) authorization DB.
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.
-delete switch, the super-user or master POP user can remove
a user entry from the authorization DB.
