Before running the statement below to add a listener to an Availability Group, does the listener name need to be pre-created in active directory?
Or does the statement below actually create the listener object in active directory?
(code sample taken from http://msdn.microsoft.com/en-us/library/hh213080.aspx#WinPermissions:
ALTER AVAILABILITY GROUP MyAg2
ADD LISTENER ‘MyAg2ListenerIvP6’ ( WITH IP ( ('2001:db88:f0:f00f::cf3c'),('2001:4898:e0:f213::4ce2') ) , PORT = 60173 );
GO
I think it's the latter, and according to the above link, the cluster-name-object needs to have Create-Object permissions in active directory for this to work.
Is my understanding correct?

You can pre create the listener Computer account and DNS record but as this link details under the Windows Permissions section, it's best to let the wizard perform this for you. The cluster service should have the permission to do this

Thank you for the reply, but I am still confused about this.
If the listener name is precreated in AD, won't we get a name conflict if we try to *add* a listener with the same name to the avail group using the SQL stmt:
ALTER AVAILABILITY GROUP myAG1
ADD LISTENER myListener1
...
I thought the above SQL actually does all the registering of the listener Computer account and DNS record in AD.
Also in Windows Server 2008 and above, it is not the cluster *service* but the cluster name object (CNO) that needs to have the CreateObjects permission in AD.
Here is another related link I found today:
I'm just trying to clear up my understanding on all this stuff that is quite new to me. 🙂
Thanks again for the input!

If the listener resources already exist then you should get a message indicating that fact.

Sorry, yes, the differerences between 2003 and 2008 :blush:

Thank you, that link refers to setting up Exchange, but should be similar to our scenario.
