> When I try to login to an IMAP server via imap/ssl/novalidate-cert, I > receive the message "Error connecting to IMAP server: [0] Error 0" > both in the user interface and in the Horde log; that message > originates on line 345 of imp/lib/IMAP/Client.php. > > > > However when I try the login with a wrong password, I get the correct > "Authentication failed" message which clearly shows that the SSL > connection works. On the other hand, I can login to the very same > server via imap/notls, without any problem, so the > imap/ssl/novalidate-cert protocol must somehow be involved in the > error outlined above. > > > > The imp/test.php page can login to that server both via imap/notls > and imap/ssl/novalidate-cert, without any problem, which clearly > shows that the installation prerequisites (such as an SSL-enabled > version of c-client) are met. > > > > Attached is a text file containing: > > - traces of the custom hook function arguments, and results, for > three login attempts as outlined above, > > - the recommendation of the imp/test.php script, > > - the pertinent declarations from imp/config/servers.php.
