Cisco Wireless iPSK

I am exploring iPSK for a college campus. We have 9800 WLCs and use ISE AAA.

One interesting features of this setup is private-group P2P blocking. My understanding is this would allow a student to use the same PSK for their non 802.1x devices and do private mDNS discovery.

There are some features lacking within ISE, including self registration and PSK management. I found their unofficial product iPSK Manager (https://community.cisco.com/t5/security-documents/ipsk-identity-pre-shared-key-manager-portal-server-for-ise/ta-p/3904265).

Does anyone have this implemented or recommend other solutions for this specific feature? We don’t plan to replace ISE, but something will be needed to augment this capability.

Thanks
