I cannot get IMAP Mail Clients - eg Thunderbird and Outlook - to authenticate to the server. They just show an error: mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.1.2, lip=192.168.1.253, TLS, session=
They find the server and its settings correctly but fail to complete with the above error (from the /var/log/imap log) each time they try.
It is a clean install with just the Active Directory setup and the mail server and horde installed;
Horde works perfectly. I also tried running webtob and sogo and they also work perfectly via their webclient.
It is a standalone server without gateway.
I have tried connecting the client using IP addresses and domain name on the LAN and WAN;
It is a FQDN with correct routing and SSL installed.
Tried ‘username’ and ‘username’@‘domain’ all with the same result;
Any suggestions as to what I may be missing? The logs suggest the connection is correct, the clients suggest the username or password is incorrect (checked and double-checked).
LetsEncrypt Michael, yet I’m going to uninstall/reinstall again as I may not have selected that as the default server cert (assuming it would just do so )
Hi Stefan. No, not using it specifically any more. I think at the time it was a preferred client to Roundcube and was offered via nethserver-horde : https://github.com/NethServer/nethserver-horde
I then seem to recall that Horde was behind in providing PHP7 support which caused some issues. I wasn’t reliant on it so moved away from it. SOGo appears to have moved ahead of Horde by leaps and bounds.
Any reason you are wanting to use Horde specifically, or are you having any issues?
Horde is still available in nethforge-testing but there were issues with TLS (you need to use older TLS policy), see Horde login problems - #5 by mrmarkuz
thank’s for your reply. Well, many years back we started to use horde as groupware. I think it’s some kind of beeing lost in the past. Right now we’re using sogo which is quite o.k.
