NAME

       sgepasswd - Modify the Grid Engine password file of Grid Engine

SYNTAX

       sgepasswd [[ -D domain ] -d user ]

       sgepasswd [ -D domain ] [ user ]

DESCRIPTION

       sgepasswd modifies the Grid Engine password file sgepasswd(5).

       This  file  contains  a  list  of  usernames  and  their  Microsoft  Windows  password in encrypted form.
       sge_execd(8) and sge_shepherd(8) on hosts  running  Microsoft  Windows  as  operating  systems  use  this
       information to start jobs for a certain user.

       Each  user  can  use  the sgepasswd application to add a new entry for their own user account.  (In fact,
       normal users can create an entry for any account, so the entry should be made initially, when the account
       is created.)  It is also possible to change the stored password with sgepasswd if the user knows the  old
       one.

       The  root  user  additionally has permission to change the password entries for other user accounts. Root
       can also delete existing entries.

       The sgepasswd binary is only available on non-Windows hosts.

OPTIONS

       -D domain
              By default sgepasswd will add/modify the current Unix username  without  a  domain  specification.
              This  switch  can be used to add a domain specification in front of the current user name. Consult
              your Microsoft Windows documentation to get more information about domain users.

       -d user
              Only root can use this parameter to delete entries from the sgepasswd(5) file.

       -help  Prints a listing of all options.

NOTE

       Prevent relevant jobs running before a password is changed both with sgepasswd and in the Windows domain.
       Otherwise, if multiple jobs try to run on a Windows host as the user concerned, and are unable to  access
       the  right  password,  Windows' intrusion detection system may disable the account.  sgepasswd and in the
       Windows domain.

SECURITY

       This is a non-trivial program which needs to be setuid root, operating with various user-supplied  input.
       It probably shouldn't be installed setuid if it is not needed to support Windows hosts.

       See above concerning making initial entries.

ENVIRONMENT VARIABLES

       SGE_KEYFILE    If   set,   specifies   the   location   of   the   private   key   file.    Default    is
                      /var/lib/sgeCA/port$SGE_QMASTER_PORT/$SGE_CELL/private/key.pem.

       SGE_RANDFILE   If  set,  specifies  the  location  of  the seed used to create encrypted versions of user
                      passwords.                                   Default                                    is
