[Freeswitch-users] xml_curl directory - doing authentication in cgi, how to recreate user's password?

[Rendy]

Hi Fraser,
What I mean is like this, when user trying to authenticate says via
your application, can you hashed the password in the same manner
before sending to Freeswitch (says MD5)? If yes, then in your php, you
should return the XML with hashed user password that you retrieve from
DB and let Freeswitch compare for you. You do not need to compare
yourself.

Hope I understand your problem correctly and this can solved it :)
