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.
