 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!

 off).
 This change disables the prompt for the change of an expired password by
 default (using the PAM_RADIO_TYPE mechanism if present).

 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).

 Subject: [PATCH 1/6] selftest: Do not force -d0 for smbd/nmbd/winbindd
 We have the env variable SERVER_LOG_LEVEL which allows you to change
 the log level on the command line. If we force -d0 this will not work.
 make test TESTS="samba" SERVER_LOG_LEVEL=10
