Hello, is GSSAPI authorization supported by timsieved? It seems that either sieveshell (which I used to test GSSAPI for sieve) or timsieved itself failed to finish GSSAPI session correctly: Nov 21 17:37:01 ****** imaps[98068]: login: dhcp250-232.****** [*.*.250.232] ****** GSSAPI+TLS User logged in Nov 21 17:37:06 ****** sieve[98007]: badlogin: dhcp250-232.****** [*.*.250.232] ****** GSSAPI error base64 decoding string [17:37][****@slayer:q3][~]$ klist Credentials cache: FILE:/tmp/krb5cc_1001 Principal: slayer@****** Issued Expires Principal Nov 21 17:30:00 Nov 22 03:30:04 krbtgt/KDC_DOMAIN@KDC_DOMAIN Nov 21 17:32:34 Nov 22 03:30:04 imap/*********@KDC_DOMAIN Nov 21 17:33:10 Nov 22 03:30:04 sieve/*********@KDC_DOMAIN In the same time imap server authenticates users perfectly, also, I think, it could be a problem in SASL library - I have found some discussions about processing CR+LF in saslutil.c - but patch I used did not help.
