SYNOPSIS

DESCRIPTION

       This command is deprecated. It is used to maintain an SRP (secure remote password) file.
       At most one of the -add, -modify, -delete, and -list options can be specified.  These
       options take zero or more usernames as parameters and perform the appropriate operation on
       the SRP file.  For -list, if no user is given then all users are displayed.

       The configuration file to use, and the section within the file, can be specified with the
       -config and -name flags, respectively.
