Un-Register ICQ from Admin interface?

I’m trying to un-register ICQ transports for certain individuals. However if I clear out/blank out the user name and password from the admin interface, the end user will be prompted again to enter correct credentials on their Spark client.

Is there a better way to do this without bugging the end user? Thanks!


Why not just delete the registration instead of blanking the username and password?

I thought it would remove the whole account (including the Openfire login, not just the registration). Sweet deal - it worked out great for what we needed to do. Thanks wroot
