[OpenSIPS-Users] Auth parameter disable_nonce_check not working as expected

[Robert Dyck]

Let me rephrase. The UA receives a 401 message from opensip. The nonce is 
reported as stale. The UA attempts again to register using the same nonce as 
previously. On and on. I calculated the digest myself and it is correct for 
the stale nonce. My thinking is that if opensips ignored the fact that the 
nonce has expired then register should succeed.
