can you apply the following patch:

http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=blobdiff;f=modules/auth/api.c;h=c79de5c9dd6cd3e176c05d836c7b0a4275f8a3d2;hp=2ee39a7a6cbcce741365dac97ae8a3db8c196b0c;hb=494b383edde7a2d193c220f3117506e4cc95932f;hpb=e4ecf49add0e62330e1db071106806e35e9b078a

It practically adds the return code in the log message, that should give 
better leads to why the nonce is considered invalid, allowing to track 
back quicker in the source code.

Cheers,
Daniel
