1) kinit with the trust keytab. The exact principals depend on your IPA
and Windows realm names, in my test setup it is:

# ls /var/lib/sss/keytabs/
win.trust.test.keytab
#kinit -kt /var/lib/sss/keytabs/win.trust.test.keytab 'IPA$@WIN.TRUST.TEST'
(the principal is taken from the keytab, see klist -k
/var/lib/sss/keytabs/win.trust.test.keytab)

2) search the DC
#ldapsearch -Y GSSAPI -H ldap://dc.win.trust.test -b dc=win,dc=trust,dc=test -s 
base 

btw at the moment it is not possible to set custom DCs to talk to. This
feature will come in the next version (sssd-1-15).
