Operating Systems AIX Poll of sorts - on LDAP Post 302843680 by MichaelFelt on Wednesday 14th of August 2013 11:28:58 AM

Thanks for your replies. Finally not in a plane, visiting customers, etc..

IDS seems daunting - but it does have the schema for supporting all AIX user attributes. Most customers I see usig LDAP and not IDS only support/use the RFC2307 (basically /etc/passwd and /etc/group entries) and rely on the files in /etc/security - in particular /etc/security/user - but never think to update them.

Also, no RBAC/TE support, by default, in non-IDS.

I doubt I will experiment with AD (what I hear is if you add the AIX schema AD is out of support) as customers do not like to "go out of support". So, when they use AD as server for AIX they use the AD equivalent of RFC2307.

I expect openLDAP to support RFC2307 - out of the box. I have been reading their documentation and am hopeful that the AIX schema can be added in without too much difficulty - since that know have a tool for configuring slapd - keeping the config info in private ldif files, similiar to how IDS does it's configuration.

Just remember, in discussions, IDS does not really need to be administered/updated in the LDAP internals if it is only being used for AIX - IDS/ITDS is already configured for AIX support. AND - when used for AIX only - there is no additional charge. FYI...

@Lerphil - are you using openLDAP with rfc2307AIX schema, or rfc2307 only?

idmap_ad

IDMAP_AD(8)						    System Administration tools 					       IDMAP_AD(8)

NAME

       idmap_ad - Samba's idmap_ad Backend for Winbind

DESCRIPTION

       The idmap_ad plugin provides a way for Winbind to read id mappings from an AD server that uses RFC2307/SFU schema extensions. This module
       implements only the "idmap" API, and is READONLY. Mappings must be provided in advance by the administrator by adding the
       posixAccount/posixGroup classes and relative attribute/value pairs to the user and group objects in the AD.

IDMAP OPTIONS

       range = low - high
	   Defines the available matching UID and GID range for which the backend is authoritative. Note that the range acts as a filter. If
	   specified any UID or GID stored in AD that fall outside the range is ignored and the corresponding map is discarded. It is intended as
	   a way to avoid accidental UID/GID overlaps between local and remotely defined IDs.

       schema_mode = <rfc2307 | sfu >
	   Defines the schema that idmap_ad should use when querying Active Directory regarding user and group information. This can be either the
	   RFC2307 schema support included in Windows 2003 R2 or the Service for Unix (SFU) schema.

EXAMPLES

       The following example shows how to retrieve idmappings from our principal and trusted AD domains. If trusted domains are present id
       conflicts must be resolved beforehand, there is no guarantee on the order conflicting mappings would be resolved at this point. This
       example also shows how to leave a small non conflicting range for local id allocation that may be used in internal backends like BUILTIN.

		[global]
		idmap backend = tdb
		idmap uid = 1000000-1999999
		idmap gid = 1000000-1999999

		idmap config CORP : backend  = ad
		idmap config CORP : range = 1000-999999
