What exact command are you using with sogo-tool? |
|
|
|
e.g. sogo-tool update-autoreply -p /etc/sogo/sieve.creds or sogo-tool user-preferences unset defaults user -p /etc/sogo/sieve.creds Forward |
|
|
|
The IMAP login (and list operation) is required to fetch the IMAP delimiter character. It falls back to NGImap4ConnectionStringSeparator. |
|
|
|
But the way it is currently implemented IMAP authentication does not work. The username and password from the admin credentials file are not necessarily valid for the IMAP LOGIN command and as a side effect sogo-tool often hangs for several minutes until Dovecot closes the unauthenticated IMAP connection. The credentials must be used with SASL PLAIN (RFC 4616) and the user that should be impersonated (authzid) must be specified like it is already done for ManageSieve. |

sogo-tool is properly doing a proxy authentication.
Sniff the traffic to see why is sogo-tool hanging. |
|
|
|
Running sogo-tool with IMAP debugging clearly shows otherwise. Hanging seems to be caused by ignoring the authentication failure and sending the next command (LIST) to quickly.
