Subject: [PATCH 1/4] s3:winbind: Do not use domain's private data to store the
SAMR pipes
The domain's private_data pointer is also used to store a ADS_STRUCT,
which is not allocated using talloc and there are many places casting
this pointer directly.
The recently added samba.tests.pam_winbind_setcred was randomly failing
and after debugging it the problem was that kerberos authentication was
failing because the time_offset passed to kerberos_return_pac() was
wrong. This time_offset was retrieved from ads->auth.time_offset, where
the ads pointer was directly casted from domain->private_data but
private_data was pointing to a winbind_internal_pipes struct.
