Matt, Thanks!
That worked...It's odd that the title for the UX is Change DOMAIN Admin when in fact we are changing the Primary Admin. It works but could be confusing as there is no reference to Primary Admin.

We've also noticed that Forwarding and deleting from the Primary Admin is hit and miss. Some emails from our test gmail accounts are not deleting or forwarding. But others internal emails are properly forwarding and then deleting from the same account. Known bug?

There is a chance it could be an impersonation bug. To test that theory you can create a temporary password for the primary admin account and logging in and trying that way. If you notice it working but then if you impersonate you see the odd behavior then it is definitely a bug relating to impersonation. I can't really see any other reason why just the Primary Admin would have issue with that as being a Primary/Domain admin/user shouldn't affect how emails are forwarded.

Without impersonating these are the logs from 2 tests I just ran:
You can see the gmail account "Delivered" while the local account (steve@sgdesign.com) was Forwarded and Deleted. I checked the person's Contacts in case there was some tie but my test account is not present in their contacts.  If you like I can still do the Impersonation Test but since I was not logged into the account it may not be any different.

Is this still an accurate way to change the Primary Admin for my entire SM Installation on a Linux box?

Stephen

Hello Stephen, 

This is still how you would adjust the domain's "Primary Administrator". Go to Manage -> Domains -> {selected-domain} -> Options [tab] -> Options [card]. 

Here you want to adjust the "Primary Domain Administrator" field. This is not a drop-down, start typing the username of the user you wish to make the Primary Admin and you will get an auto-complete list based on the domain's account list.  

Thank you

Tony, thanks for this reply. I might be confused or seeking a different answer for this thread. I am not trying to change the primary admin for a single domain, but instead the primary administrator account for the entire Smarter tools installation. I have a Debian install, do you know if there are instructions for how that task is accomplished?

To change the administrator for the system.

Log in.

Go to settings.

Click Administrators.

Thank you for this reply, but unless I"m missing it,  there is nothing in these knowledgebase instructions, or the the online help,  that tells how to change the Primary Administrator.  

Here a screenshot:

Hello, 

You are not able to re-assign the "Primary System Administrator", what you can do is to edit it by changing the name and password.

Thank you
