Limiting Login Computers and Openfire LDAP Authentication

I recently took a department in out AD domain and set them to only be able to log into specific computers. While this was up, Spark, the LDAP SASL connection could not authenticate them to the Openfire Server. I tried adding the Openfire server to the list of allowed machines to log into but this also did not allow them to authenticate. As soon as I removed the computer restrictions the users were able to authenticate to the Openfire Server through Spark.

Any ideas why this is? I’m also not sure whether this is a Spark Issue or an Openfire issue.

This is an error that is found under the Info tab on the Server.
