After googling a bit I found a <a href=\"http:\/\/llbb.wordpress.com\/2007\/07\/11\/ssh-takes-exactly-1-minute-20-seconds-or-80-seconds\/\">post describing my problem<\/a> which I would like to recommend to the public. Root cause seems to be a missing configuration of the GSSAPI module. Instead of configuring it you may also simply disable this authentification method in \/etc\/ssh\/sshd_config by specifying<\/p>\n<pre>\r\n# GSSAPI options\r\nGSSAPIAuthentication no\r\n#GSSAPIAuthentication yes\r\nGSSAPICleanupCredentials no\r\n#GSSAPICleanupCredentials yes\r\n<\/pre>\n<p>That solved my problem immediately.<br \/>\nHowever, against what&#8217;s written in the wordpress post, I had another error behaviour:<\/p>\n<pre>\r\ndebug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password\r\ndebug1: Next authentication method: gssapi-with-mic\r\ndebug1: Unspecified GSS failure.  Minor code may provide more information\r\nCredentials cache file '\/tmp\/krb5cc_0' not found\r\n\r\ndebug1: Unspecified GSS failure.  Minor code may provide more information\r\nCredentials cache file '\/tmp\/krb5cc_0' not found\r\n\r\ndebug1: Unspecified GSS failure.
