I'm having some problems with clients linked against Cyrus SASL 2.1.22. Running imtest linked against 2.1.22 against an cyrus-imapd server (also linked against 2.1.22) with GSSAPI authentication shows: C: A01 AUTHENTICATE GSSAPI BLAHBLAHBLAH S: + BLAHBLAHBLAH Authentication failed. generic failure Security strength factor: 0 and this in the imap logs: May 23 15:48:01 pobox09 imap[26261]: badlogin: pobox09.stanford.edu [171.67.22.15] GSSAPI [SASL(0): successful result: security flags do not match required] Same happens with Kerberos 4. PLAIN and LOGIN both work fine, which indicates that saslauthd is running fine against GSSAPI. Note that running the 2.1.22 client against a 2.1.21 server gives the same thing whereas running the 2.1.21 client against the 2.1.22 server is working fine. Any ideas? Do I have to rebuild the clients against the 2.1.22 libraries to pick up an API change or something? -- Huaqing Zheng Beer and Code Wrangler at Large
