Failing Password Change

I've got a pair of LTMs staged for installation, but no network hooked up yet. But I have a console connection. The LTMs are configured for Active Directory authentication.

I try to change the root password: 

  
  [root@:Active] config  passwd root  
  Changing password for user root.  
  New BIG-IP password:  
  Retype new BIG-IP password:  
  Changing password for user root.  
  passwd: Authentication token manipulation error  
  Failed to change user's password.  Exiting.

/var/log/secure indicates this: 

Sep 11 16:41:48 zdxbig1 passwd(pam_unix)[11270]: new password not acceptable

Anyone seen this before? The password I am entering is accepted by other pairs of LTMs running the same software (9.3.1HF1).

    Interestingly, I do not see the dialog box referenced in the article you linked to.

     

     

    However I did get this to change. Since there was no network cable and I wasn't close to the console port, I had to use this fancy IP-based console connection software which I was connected to while changing the password. However today I connected directly to the management interface, and that allowed me to change the password. I did notice after looking more closely that I skip right past the second password prompt when using the IP-console. This funky console software must be adding some characters at the end.

     

     

    Anyway it's resolved.
