Thanks, these logs have somewhat more info than those in the other
thread.

It seems that Winbind on the IPA server has trouble talking to the AD
server:

(Thu Jan 2 19:27:41 2014) [sssd[be[wibble.com]]] [fo_set_port_status]
(0x0100): Marking port 0 of server 'ipa.wibble.com' as 'working'
(Thu Jan 2 19:27:41 2014) [sssd[be[wibble.com]]]
[set_server_common_status] (0x0100): Marking server 'ipa.wibble.com' as
'working'
(Thu Jan 2 19:27:41 2014) [sssd[be[wibble.com]]] [ipa_s2n_get_user_done]
(0x0040): s2n exop request failed.

(The s2n exop does a special LDAP call to IPA which in turn calls
winbind on the server).

To generate the winbind logs on the server, can you do 'smbcontrol winbindd
debug 100', then request the trusted user. The winbind logs would be at
/var/log/samba/log.w*

Don't use debug level 100, it will litter the tmp with packet dumps and
[possibly fill the disk.

Log level 10 is the max that is ever useful.
No, you are not right.

It looks in this case that there are some unfinished async tasks
associated with the outgoing socket and they prevent cli_negprot from
starting. On debug level 100 we see content of the packets sent by
smbd/winbindd in the log itself which will help to identify what
happens. On debug level 10 we simply have two lines in succession
telling that winbindd attempted to start cli_negprot and then failed it.
