The "idmap_hash" module now works correctly when used with other modules
Previously, the "idmap_hash" module worked incorrectly when it was used together with other modules. As a consequence, user and group IDs were not mapped properly. A patch has been applied to skip already configured modules. Now, the hash module can be used as the default idmap configuration back end and IDs are resolved correctly.

Description of problem:
idmap_hash module works incorrectly when used with other backend modules
Version-Release number of selected component (if applicable):
samba 4.2
How reproducible:
Mapping is configured as
idmap config * : range = 100000-2139999999
idmap config * : backend = hash
idmap config DOM002 : range = 2140000000-4290000000
idmap config DOM002 : backend = rid
Steps to Reproduce:
1. # wbinfo -i dom001+user1 <---- dom001
dom001+user1:*:1650596368:2140000513:user1:/home/user1:/bin/ksh
# wbinfo --uid-to-sid=1650596368
S-1-5-21-126432666-1270913926-3679153413-137744
# wbinfo --sid-to-name S-1-5-21-126432666-1270913926-3679153413-137744
DOM002+user1 1 <--- dom002
2.
3.
Actual results:
Expected results:
DOM002+user1 gets id from 214 range not below
Additional info:
Changing component, there is no samba4 in RHEL7 anymore only samba

In the global section add:
idmap config * : range = 10000-20000
idmap config * : backend = hash
idmap config YOURDOMAIN : range = 30000-40000
idmap config YOURDOMAIN : backend = rid
If you now get a unix ID for YOURDOMAIN, it should be from the range 30000-40000 but before fixing the issue it was in the range 10000-20000.
wbinfo -i YOURDOMAIN+user1
