BAM Issue: Auth Failures & Unauthorized subscribers

Currently have issues with our 900SM’s, once installed seem to have auth failures. We are finding we have to turn off the authentication on the AP’s to keep customers online. Anyone else seen issues such as these?
We use BAM, customers MAC’s are correctly loaded into BAM, but some that are in BAM are showing up in unauthorized subscribers??

I’m using 900 gear with BAM and not having any such issues.

It sounds to me like data is getting blocked between your BAM server and the AP(s) in question.

Make sure you have a clean network path between the two, double check any possible port blocking, rule out a NAT issue.

Hope that helps
