Thanks for the response!!
Here's what I have so far. I don't yet know the syntax so I'm just trying to write something that seems reasonable. ---------- Post updated at 07:46 AM ---------- Previous update was at 07:38 AM ----------
Any suggestions on what I should do next? I realize I have to learn Bash script syntax but does the basic logic seem reasonable? I know it's a bit simplistic but I figure I should get something to work for my first script and then add features later...

Wow, actually, my script worked. I'm shocked. It's not fancy but it basically did what i wanted. I have to improve it for sure.

I'd like to get some opnions on choosing DNS server:
Windows DNS vs Linux BIND comparrsion:
1) managment, easy of use
2) Security

Hi,
I have a question on how to point the DNS server-1's A-record to second DNS server, which is DNS server-2. So, the computer can access other domain which only listed in the DNS server-2. The scenario is as follow:

I am trying to setup a CentOS 6.2 server that will be doing 3 things DHCP, DNS & Samba for a very small office (2 users). The idea being this will replace a very old Win2k server. The users are all windows based clients so only the server will be Linux based.

idmap_autorid
IDMAP_AUTORID(8) System Administration tools IDMAP_AUTORID(8)NAME
idmap_autorid - Samba's idmap_autorid Backend for Winbind
DESCRIPTION
The idmap_autorid backend provides a way to use an algorithmic mapping scheme to map UIDs/GIDs and SIDs that is more deterministic than
idmap_tdb and easier to configure than idmap_rid.
The module works similar to idmap_rid, but it automatically configures the range to be used for each domain, so there is no need to specify
a specific range for each domain in the forest, the only configuration that is needed is the range of uid/gids that shall be used for
user/group mappings and an optional size of the ranges to be used.
The mappings of which domain is mapped to which range is stored in autorid.tdb, thus you should backup this database regularly.
Due to the algorithm being used, it is the module that is most easy to use as it only requires a minimal configuration.
IDMAP OPTIONS
rangesize = numberofidsperdomain
Defines the number of uids/gids available per domain range. The minimum needed value is 2000. SIDs with RIDs larger than this value
will be mapped into extension ranges depending upon number of available ranges. If the autorid backend runs out of available ranges,
mapping requests for new domains (or new extension ranges for domains already known) are ignored and the corresponding map is
discarded.
Example: with rangesize set to 10000, users/groups with a RID up to 10000 will be put into the first range for the domain. When
attempting to map the an object with a RID of 25000, an extension range will be allocated that will then be used to map all RIDs from
20000-29999.
One range will be used for local users and groups and for non-domain well-known SIDs like Everyone (S-1-1-0) or Creator Owner
(S-1-3-0). A chosen list of well-known SIDs will be preallocated on first start to create deterministic mappings for those.
Thus the number of local users and groups that can be created is limited by this option as well. If you plan to create a large amount
of local users or groups, you will need set this parameter accordingly.
The default value is 100000.
read only = [ yes | no ]
Turn the module into read-only mode. No new ranges will be allocated nor will new mappings be created in the idmap pool. Defaults to
no.
ignore builtin = [ yes | no ]
Ignore any mapping requests for the BUILTIN domain. Defaults to no.
THE MAPPING FORMULAS
The Unix ID for a RID is calculated this way:
ID = REDUCED RID + IDMAP RANGE LOW VALUE + RANGE NUMBER * RANGE SIZE
where REDUCED RID = RID % RANGE_SIZE and a DOMAIN RANGE INDEX = RID / RANGE_SIZE is used together with the domain sid to determine the
RANGE NUMBER (stored in the database).
Correspondingly, the formula for calculating the RID for a given Unix ID is this:
RID = (ID - LOW ID) % RANGE SIZE + DOMAIN RANGE INDEX * RANGE SIZE
Where the DOMAIN RANGE INDEX is retrieved from the database along with the domain sid by the RANGE NUMBER = (ID - LOW ID) / RANGE SIZE .
EXAMPLES
This example shows you the minimal configuration that will work for the principal domain and 19 trusted domains / range extensions.
[global]
security = ads
workgroup = CUSTOMER
realm = CUSTOMER.COM
idmap config * : backend = autorid
idmap config * : range = 1000000-1999999
This example shows how to configure idmap_autorid as default for all domains with a potentially large amount of users plus a specific
configuration for a trusted domain that uses the SFU mapping scheme. Please note that idmap ranges and sfu ranges are not allowed to
overlap.
[global]
security = ads
workgroup = CUSTOMER
realm = CUSTOMER.COM
idmap config * : backend = autorid
idmap config * : range = 1000000-19999999
idmap config * : rangesize = 1000000
idmap config TRUSTED : backend = ad
idmap config TRUSTED : range = 50000 - 99999
idmap config TRUSTED : schema_mode = sfu
