No. 

What I did was change the first few to see what happens. And still the
first 13 (this time, last time 17) failed. I am baffled why the first 11
to 17 fail (randomly) and the remainder receive "Successfully granted
rights."

If I have any issues, I'll be back. --- ------------------------- Bob Wooden of Donelson Trophy 615.885.2846 (main) www.donelsontrophy.com [1] [1 [1]] "Everyone deserves an award!!"

Being the novice that I am, I thought the line would 'pickup' my DOMAIN and replace the ${SAMBA_NT_DOMAIN}. So, I just tried the line correctly and it asked for my Administrator password and subsequently granted access. At least I know I can go and correct manually, if I need too. My /etc/resolv.conf is: root at dt01:~# cat /etc/resolv.conf search dts***m.dt nameserver 192.168.16.51 The nameserver is resolving to "itself",
  the
DC01. (As you know, this is created through the script.) The "wbinfo -g" says that "Domain Admins" is indeed in the groups. --- ------------------------- Bob Wooden of Donelson Trophy 615.885.2846 (main) www.donelsontrophy.com [1] [1 [1]] [1 [1]] "Everyone deserves an award!!"

Generally there are anywhere from 12 to 17 failures across two attempts (that I paid clos
 e
attention too, out of five tries.) And, because I have two identical computers (one that will become DC1 and the other DC2) I switched machines, just to make sure it wasn't a hardware issue. It's not! When I run one of the failed script line manually, I get: root at dc01:~# echo ${SAMBA_NT_ADMIN_PASS}| net rpc rights grant "${SAMBA_NT_DOMAIN}Domain Admins" SeDiskOperatorPrivilege -UAdministrator Enter Administrator's password: Could not connect to server 127.0.0.1 The username or password was not correct. Connection failed: NT_STATUS_LOGON_FAILURE That might have failed because . . . . so, I tried this: root at dc01:~# net rpc rights grant "${SAMBA_NT_DOMAIN}Domain Admins" SeDiskOperatorPrivilege -UAdministrator Enter Administrator's password: Failed to grant privileges for Domain Admins (NT_STATUS_NO_SUCH_USER) So, the script is not creating the "Domain Admins"? Confused, for sure!!!! Hi Bob, what have you got in /etc/resolv.conf ? I also take it that when you ran the lines manual
 ly, you
replaced the variables with the correct info. The script doesn't create Domain Admins, this is done by the provision, run 'wbinfo -g' this should print all your domain groups. Rowland Links: ------ [1] http://www.donelsontrophy.com [1] [1 [1]]
 OK, I have had a look at Louis's script and the line that is failing is
this: echo ${SETNTPASSWD}| net rpc rights grant ${SETNTDOM}"Domain
Admins" SeDiskOperatorPrivilege -UAdministrator I 'think' the problem is
here ^ If you want to escape a character in bash you use the ''
character and I 'think' what is happening is that, instead of escaping
the other '' it is actually escaping the double quotes character Try
replacing that line with this: echo ${SETNTPASSWD}| net rpc rights grant
${SETNTDOM}Domain Admins SeDiskOperatorPrivilege -UAdministrator Rowland

I am convinced it is the way that line is formatted, instead of using
DOMAINDomain Admins, I think it is using DOMAINdomain, so perhaps this
would be better:

echo ${SETNTPASSWD}| net rpc rights grant "${SETNTDOM}\Domain Admins"
SeDiskOperatorPrivilege -UAdministrator

but as you are now up and running, we will probably never know.
