Adding your tip to the smb.conf did the trick.
[global]
client signing = mandatory
client use spnego = yes
kerberos method = secrets and keytab
net join ads and the keytab is written and can be used by sssd. Also the
timestamps are from now and not the 70ties. So seems to work with 2003 SFU.
Perfect & thanks a lot :)
You might add "klist -kte" and "net ads status/info" also to the documentation
as they help a lot verifying what's happening.
Sorry question anyway: using the keytab just eases the issue with plaintext
binding credentials, but is actually still an 'weakness': stealing this key
enables you to the active-directory from anywhere, anyway, not?
Is there a scenario where the 'challenging' username/passwd is taken to
authenticate against the AD? E.g. the credentials I just ssh/pam-entered are
used against LDAP instead of any pre-configured credentials?
Cheers

Will update the article with some more notes on this tomorrow. My config was
for samba 3.5, I don't know what version you're running. You definitely need
the keytab line in your config (that line is different in 3.0 but you'll find
it in the man page).
Once you've done that, join the domain again, and /etc/krb5.keytab should be
created, and yes, that's what sssd uses.
