I have setup SER to authenticate via FreeRADIUS with MSSQL DB. The SIP proxy (SER) use digest authentication to authenticate with FreeRADIUS server. This way the user's password is stored as cleartext in the database. I'd like to know is there a way to make such setup using hashed password (just MD5 or HA1)? I asked this question on SER's mailing list, but seems cleartext password is the only way to do digest authentication with FreeRADIUS. After reading through RFC2617 and draft-ietf-radext-digest-auth-04, seems to me that if Digest-Algorithm attribute in RADIUS packet is 'MD5-sess', there is a Digest-HA1 attribute might be useful for my purpose. Is there any options to tweak FreeRADIUS's digest authentication mode, something like 'auth_type' or 'encrypt_method' for MSCHAP or other authentication methods? Thanks.
