Hi all, I'm trying to put toghether one way to register softphones into openser doing the users authentication in IAS. I would like to put some questions into the list in way to clear out my doubts. 1 Can radiusclient-ng authenticate in IAS ???? If so how? I've tried it and IAS says that there is an malformed radius message. 2 Putting freeradius in the midlle of the radiusclient-ng and IAS shoud he act as a proxy between the radiusclient-ng and the IAS? this configuration works? has anyone done it? Thanks in advance for all the help that anyone can give
