I have the problem that all files on NFS-Shares are only accessible by the user qqeda11 (unix-id 79846).
All users get mapped to qqeda11  with usermap qqeda11=*.
But the user qqeda11 is also known in the MUC-Domain as windows user (muc/qqeda11 SID= S-1-5-21-43206524-2104247658-1151357142-1581344): 

To achieve the correct mapping, I have added a mapping to winbindd_idmap.tdb:

	dumping id mapping from /lfs/EDA/DATA/SOFTWARE/samba/var/locks/winbindd_idmap.tdb
	GID 79846 S-1-5-21-43206524-2104247658-1151357142-513
	USER HWM 79846
	UID 79846 S-1-5-21-43206524-2104247658-1151357142-1581344
	GID 79847 S-1-1-0
	GID 79848 S-1-5-2
	GROUP HWM 79849

Does this correspond with your explanation of id ranges?
