 If only one range is configured we are either not able to map users/groups
 from our primary *and* the BUILTIN domain. We need at least two ranges to also
 cover the BUILTIN domain!

 Subject: [PATCH 6/6] s3:winbind: Use the canonical principal name to renew the
 credentials
 The principal name stored in the winbindd ccache entry might be an
 enterprise principal name if enterprise principals are enabled. Use
 the canonical name to renew the credentials.

 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.

 Subject: [PATCH 2/5] s3:passdb: Add support to handle UPNs in lookup_name()
 This address an issue if sssd is running and handling nsswitch. If we look up
 a user with getpwnam("DOMAIN\user") it will return user@REALM in the passwd
 structure. We need to be able to deal with that.

 From 10f485b3a27e10906aa6ee40833fca8bf81b5511 Mon Sep 17 00:00:00 2001
 From: Stefan Metzmacher <metze@samba.org>
 Date: Sat, 22 Jan 2022 01:08:26 +0100
 Subject: [PATCH] dcesrv_core: wrap gensec_*() calls in [un]become_root() calls
 This is important for the source3/rpc_server code as it might
 be called embedded in smbd and may not run as root with access
 to our private tdb/ldb files.
 Note this is only really needed for 4.15 and older, as
 we no longer run the rpc_server embedded in smbd,
 but we better be consistent for now.
 This should be able to fix the problem the printing no longer works
 on Windows 7 with 2021-10 monthly rollup patch (KB5006743).
 Windows uses NTLMSSP with privacy at the DCERPC layer on top
 of NCACN_NP (smb).
 BUG: https://bugzilla.samba.org/show_bug.cgi?id=14867
 Signed-off-by: Stefan Metzmacher <metze@samba.org>
 Reviewed-by: Andreas Schneider <asn@samba.org>
