I tried with my GSSAPI test bed and i cannot reproduce the issue.
I tried [next] but GSSAPI has not changed for long, so i am a bit
out of ideas, especially given the actual error you mention.
I know i sometimes can force timeouts because the GSSAPI code
seems to use getaddrinfo(3), and the GNU C library will try to
fetch IPv4 and IPv6, and waits to collect the results ... I maybe
should try to configure this beast. Well. Other than that ...
dunno, sorry; i really can send adjacent mails without issue:
