While PLAIN authentication works fine, I had the https daemon crash during DIGEST-MD5 authentication. The crash turned out to be a divide error in libdigestmd5 from cyrus-sasl. In particular (in cyrus-sasl’s plugins/digestmd5.c): /* Create an initial cache entry for non-persistent HTTP connections */ unsigned val = hash((char *) nonce) % text->reauth->size; would fail due to text->reauth->size being zero. If I’m reading this correctly, this appears to be the effect of initializing the plugin (as done in digestmd5_server_plug_init(), defined in same file as the snippet above) with an undefined reauth_timeout. And indeed, adding "sasl_reauth_timeout: 10” to /etc/imapd.conf makes the crash go away. I didn’t expect a configuration without reauth_timeout to crash imapd, but I haven’t done enough research to be sure, nor to tell where the problem lies should this be a real issue. Any further insight is greatly appreciated! // Cheers; Johan ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
