Hello to all! Here is my problem: I can't send e-mails from my Kubuntu 7.04 desktop PC, using Kmail e-mail client. When i push "Send button", following Kontact error appears: "Sending failed: Authorization failed, An error occured during authentication: SASL(-4): no mechanism available: No worthy mechs found authentication not supported The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport protocol was used: send_smtp" ...and the mail is not send! The "security settings" for my mail send account are: Encryption: TLS Authentication Method: Plain Important details about this issue: 1) This e-mail sending error appears only when I'm authenticate against LDAP server (the network I'm in has NFS-mounted home dirs and LDAP authetication). When I use a local user (or root user), everything works right! 2) This error appears only in Kubuntu 7.04. I know this because I tested the same system configuration settings(including LDAP auth enabled) in Kubuntu 6.06 + kmail and the mail-sending worked just FINE! If anybody had this problem after upgrading/replacing 6.06 -> 7.04, or know smthing about it, please let me know(i googled awhile, but no relevant results for me) !!! PS: I can give more details about my config, just ask me Thanks in advance!
