This looks to be a generic winbind and domain joining issue, which
probably doesn't have anything to do with CTDB.  Phew...  :-)

Searching for "Could not fetch our SID - did we join?" gets a bunch of
hits, including this one:

 
http://samba.2283325.n4.nabble.com/Winbind-error-quot-Could-not-fetch-our-SID-did-we-join-quot-td4726277.html

Did you use "net ads join" to join the domain?  What does "net
ads
testjoin" say?

peace & happiness,
martin

[Samba] CTDB Question w/ Winbind

Martin,

Here you go,

# echo "mypassword" | net --no-dns-updates -U service-account-name ads
testjoin domain.local

kerberos_kinit_password NETBIOS_NAME$@DOMAIN.LOCAL failed: Client not found
in Kerberos database

Join to domain is not valid: The name provided is not a properly formed
account name.
