There is a known bug/issue in the current implementation of mod_digest regarding the nonce. I am looking to have this plugged for our next 1.3 release.
There are 2 suggested patches, which I will post under separate Emails. I will also adjust STATUS to reflect these 2 potential patches.
PLEASE look these over! I would still like to get a 1.3 release out soon. My expectation is that we will toss 1.3.30...
