Solution  1008486.1 :   Sun StorageTek[TM] 5000 Series NAS: Offline Creation of CIFS/NFS (Windows/UNIX) User Credential Maps for an Entire Windows Domain

Description
By default, credential mappings (UNIX UID to Windows RID) are not created until the first time that each Windows user or group connects to the NAS server. We received several requests for the ability to create these mappings when initially installing the system, so that security and quotas could be configured prior to users connecting to the system. In response to these requests, the makemap utility was created.


Steps to Follow
The makemap.exe utility can be found in the /cvol/nf1 directory on the NAS, (If not present, check /cvol/nf2.) To use this utility, proceed as follows:

• Log into a Windows workstation as a member of the Domain Admins group.
• Copy the makemap.exe file to the workstation. Do this by using ftp or creating a Windows share.
• Open a command prompt and run the utility using the following syntax:

 Usage: makemap <Domain Name> <\\PDC Name> [/u] [/g]
/u: generate users.map file
/g: generate group.map file 

 (PDC Name = Primary Domain Controller hostname or IP address)

• Run the utility twice, once with the /u option and once with the /g option. The output of this will be a complete, NAS-compatible users.map and group.map file.

• Edit the files. To use these files, they must to be edited, as the file will initally be populated with system generated UNIX user names and UIDs. The files consist of one plain-text line per user or group with the following format:

 users.map

 unixusername:UID:windowsusername:DOMAIN:RID

 group.map

 unixgroupname:GID:windowsgroupname:DOMAIN:RID

• When editing the file, edit only the first two fields, the UNIX user/group name and UID/GID. The last three fields are automatically obtained from the Windows Domain Controller and the mappings may not work if modified.

• After editing is complete, the files should be copied to /dvol/etc. For cluster models, the file must be copied to both heads. Overwrite any existing users.map or group.map files.

• After the files have been copied, reboot the NAS (both heads for a cluster). You can then proceed to configure user quotas, home directories (using NAS command line mkdir, chown and chmod commands) or any other user-based configuration.
