Last post just to close up. Everything is fine now.
I believe the problem here stemmed from a couple of issues surrounding the GAL. We had (I changed this) the GAL for this domain setup to only use and External LDAP server. It doesn't look like the ZCB plugin will pick up modifications to users if you are using an External GAL. I changed the domain GAL setting to be Both (for internal/external) then updated the user account and ZCB picked the change right up.
Thanks for the replies.
