imsconnutil -k -u not working and some imap idle questions.

I'm working with imsconnutil to be able to boot users out of IMAP.  
But, I can't seem to get it to work.

I've successfully enabled IMAP IDLE and verified it's working:

[amail011:...sbin] root[205]# telnet ams011.mac.com 143
Trying 10.150.81.139...

Messaging Server 6.3-4.01 (built Aug  3 2007; 64bit))

I've also logged in via telnet and idled and got a new message  
notification so, I'm pretty sure it's set up properly yet,  
imsconnutil -k -u fails to disconnect me. It says it's doing it:

[amail011:...sbin] root[202]# ./imsconnutil -k -u cvervais

disconnecting cvervais

And I verified it knows I'm logged in:

[amail011:...sbin] root[211]# ./imsconnutil -c -s imap -u cvervais

I also noticed that while I had two sessions idling, only one of them  
got the new message notification. The connections were coming from  
different IPs which I think might be relevant. Is IDLE setup to only  
notify one connection or should it be notifying all?

Or, should I open a case for this?
