Using N1GE in a Microsoft Windows Environment

The N1GE execution environment has to start jobs on behalf of the submitting user. The execution daemon (sge_execd) on UNIX hosts runs as the user root so it can start jobs on behalf of all users.

On Windows Hosts the execution daemon runs as the local Administrator user so it can start jobs for local users without knowing their passwords. However, to start a job for a domain user, the execution daemon needs the password for that domain user. To facilitate this process, each user with a domain account needs to have their corresponding Windows password registered with N1GE.

Registering Windows Domain User Passwords

Domain users who want to start N1GE jobs on Windows execution hosts register their Windows passwords with N1GE using the sgepasswd client application. The following example shows Peter who has a user account in the domain ENGINEERING registering his Windows password.

> sgepasswd -D ENGINEERING
   Changing password for ENGINEERING+Peter
   New password:
   Re-enter new password:
   Password changed

Using the sgepasswd Command

sgepasswd modifies the Grid Engine password file (sgepasswd(5).) This file contains a list of usernames and their Windows passwords in encrypted form. You can use the sgepasswd to add a new entry for your user account or change your existing password. Additionally, the root user can change or delete the password entries for other user accounts. sgepasswd is only available on non-Windows hosts. It has the following syntax:

sgepasswd [[ -D domain ] -d user ]

       sgepasswd [ -D domain ] [ user ]

This command has these options:

Additionally, The following environment variables affect the operation of this command.
