NFS share and groups
I am having an issue with getting the proper group settings on NFS-shared directories.
NFS server, NFServe, nfs-shares hundreds of project directories...running Solaris 10 latest patches/updates.
SAS server, SAServe, statistical analysis server running on RedHat 7 with latest kernel/patches/etc.
NFServe uses ancient Sun Directory Server for LDAP.
SAServe uses Active Directory on win2008r2. UIDs and GIDs set up matching on LDAP/Unix/AD (so if you are group ibex GID 5005 on LDAP, you are group 5005 on AD).
NFServe also nfs-shares project directories to an old SAS server also running Solaris 10 and all groups are correct.
On SAServe, all but six of the nfs-shared directories show the proper groups. However, on six of them, the group is nobody.
Does anyone have any suggestions where to look? I can't find the problem, and I can't find anything that makes these groups/directories unique.

idmap_rfc2307
IDMAP_RFC2307(8) System Administration tools IDMAP_RFC2307(8)
NAME
idmap_rfc2307 - Samba's idmap_rfc2307 Backend for Winbind
DESCRIPTION
The idmap_rfc2307 plugin provides a way for winbind to read id mappings from records in an LDAP server as defined in RFC 2307. The LDAP
server can be stand-alone or the LDAP server provided by the AD server. An AD server is always required to provide the mapping between name
and SID, and the LDAP server is queried for the mapping between name and uid/gid. This module implements only the "idmap" API, and is
READONLY.
Mappings must be provided in advance by the administrator by creating the user accounts in the Active Directory server and the posixAccount
and posixGroup objects in the LDAP server. The names in the Active Directory server and in the LDAP server have to be the same.
This id mapping approach allows the reuse of existing LDAP authentication servers that store records in the RFC 2307 format.
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.
ldap_server = <ad | stand-alone >
Defines the type of LDAP server to use. This can either be the LDAP server provided by the Active Directory server (ad) or a
stand-alone LDAP server.
bind_path_user
Specifies the bind path where user objects can be found in the LDAP server.
bind_path_group
Specifies the bind path where group objects can be found in the LDAP server.
user_cn = <yes | no>
Query cn attribute instead of uid attribute for the user name in LDAP. This option is not required, the default is no.
cn_realm = <yes | no>
Append @realm to cn for groups (and users if user_cn is set) in LDAP. This option is not required, the default is no.
ldap_domain
When using the LDAP server in the Active Directory server, this allows to specify the domain where to access the Active Directory
server. This allows using trust relationships while keeping all RFC 2307 records in one place. This parameter is optional, the default
is to access the AD server in the current domain to query LDAP records.
ldap_url
When using a stand-alone LDAP server, this parameter specifies the ldap URL for accessing the LDAP server.
ldap_user_dn
Defines the user DN to be used for authentication. The secret for authenticating this user should be stored with net idmap secret (see
net(8)). If absent, an anonymous bind will be performed.
ldap_realm
Defines the realm to use in the user and group names. This is only required when using cn_realm together with a stand-alone ldap
server.
EXAMPLES
The following example shows how to retrieve id mappings from a stand-alone LDAP server. 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 config * : backend = tdb
idmap config * : range = 1000000-1999999
idmap config DOMAIN : backend = rfc2307
idmap config DOMAIN : range = 2000000-2999999
idmap config DOMAIN : ldap_server = stand-alone
idmap config DOMAIN : ldap_url = ldap://ldap1.example.com
idmap config DOMAIN : ldap_user_dn = cn=ldapmanager,dc=example,dc=com
idmap config DOMAIN : bind_path_user = ou=People,dc=example,dc=com
idmap config DOMAIN : bind_path_group = ou=Group,dc=example,dc=com
