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).
