HP CIFS Server Administrator Guide Version A.02.04.04 (5070-6710, October 2011)

Configuring and Using idmap rid
To use the idmap rid method, you must configure the following parameters in the smb.conf
file:
• Set idmap backend to rid:<domain name>=<idmap_rid range>.
• Set allow trusted domains to No.
An example of smb.conf using rid is shown below:
[global]
workgroup = DomainA # Doamin name
security = domain or ADS
# idmap section
idmap uid = 50000-60000
idmap gid = 50000-60000
idmap backend = rid:DomainA=50000-60000
allow trusted domains = no
Check the log file to see if the rid shared library is loaded after you configure and setup rid.
LDAP Backend Support
When multiple CIFS Servers participate in a Windows NT or Windows ADS domain and make
use of winbind, you can configure multiple CIFS Servers to store ID maps in an LDAP directory.
Making use of an LDAP server and configuring CIFS servers with the idmap backend parameter
in smb.conf will ensure that all UIDs and GIDs are unique across the domain. This is important
in order to support Windows access to NFS shares.
NOTE: The HP CIFS Server does not support the ad option for idmap backend. For Windows
ADS environments, you can consider to use idmap rid. See the “idmap rid Backend Support”
section for detailed information
Configuring the LDAP Backend
To manage ID maps in an LDAP backend server, set idmap backend = ldap:ldap://<LDAP server
name>. The following is an example of /etc/smb.conf file which has machine
ldaphostA.company.com as the idmap backend:
[global]
workgroup = DomainA # Doamin name
security = domain
# idmap section
ldap user suffix = ou=Pepole
ldap group suffix = ou=Groups
idmap uid = 50000-60000
idmap gid = 50000-60000
idmap backend = ldap:ldap://ldaphostA.company.com
ldap idmap suffix = Idmap
ldap admin dn = "cn=Directory Manager"
ldap suffix = dc=org, dc=company, dc=com
Starting and Stopping Winbind
This section describes how to start or stop the HP CIFS Server with winbind support.
Starting Winbind
Use the startsmb -winbind or startsmb -w command to start the winbind daemon on the
HP CIFS server as follows:
$ startsmb -winbind
