Hi all, I try to get GSSAPI working for sieve. I already found there was an issue with GSSAPI in dovecot 2.4 and applied the patch from this thread
https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/MWCLQCVEMHHIDHS54IKKRKGDGQQ6AGTV/#MWCLQCVEMHHIDHS54IKKRKGDGQQ6AGTV With the patch GSSAPI now works for imap. I do test this with "imtest" from cyrus tools imat@speedy:~> imtest -v -p 143 -u imat -m GSSAPI manitou.disconnected.homeip.net S: * OK [CAPABILITY IMAP4rev1 LOGIN-REFERRALS ID ENABLE IDLE SASL-IR LITERAL+ STARTTLS LOGINDISABLED AUTH=GSSAPI] Dovecot ready.

The "base64 decoding error" probably is unrelated as it does try to decode the "S: BYE .....". I also tested with other sieve clients, none does work (however different issues reported), while all tested imap clients do work. My guess is some small fix like the one from above is also needed for dovecot-pigeonhole. This is my used config manitou:~ # dovecot -n # 2.4.1-4 (7d8c0e5759): /etc/dovecot/dovecot.conf # Pigeonhole version 2.4.1-4 (0a86619f) # OS: Linux 6.14.6-1-default x86_64 # Hostname: manitou.disconnected.homeip.net # 4 default setting changes since version 2.4.0 dovecot_config_version = 2.4.0 auth_debug = yes auth_debug_passwords = yes auth_gssapi_hostname = manitou.disconnected.homeip.net auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = plain login gssapi dovecot_storage_version = 2.4.0 protocols { imap = yes lmtp = yes sieve = yes } protocol lmtp { auth_username_format = %{user | username} mail_plugins = sieve } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { } } namespace inbox { mail_driver = maildir mail_inbox_path = ~/Maildir/.INBOX mail_path = ~/Maildir inbox = yes separator = / } passdb pam { service_name = dovecot } userdb passwd { use_worker = yes } ssl_server { cert_file = /etc/ssl/servercerts/servercert.pem key_file = /etc/ssl/servercerts/serverkey.pem } service managesieve-login { } service managesieve { } sieve_script personal { active_path = ~/.dovecot.sieve path = ~/.sieve } What logs/infos are needed to dig into it ? thanks and regards, Tami
