sasldblistusers - list users in sasldb
sasldblistusers is used to list the users in the SASL password database (usually /etc/sasldb). This will NOT list all the users in /etc/passwd, shadow, PAM, etc. only those created by SASL (via saslpasswd).
KNOWN BUGS This only works for sasldb files that use the gdbm library. SEE ALSO rfc2222 - Simple Authentication and Security Layer (SASL)
