Running HA-SSO (8.0.X)and have been experiencing issues since October. Multiple engineering releases have been provided by Cisco, the latest caused HA pairs to crash. That release was promptly downgraded.
HA-SSO is a great feature, but I have heard of multiple institutions running into problems since its inception. If you aren't experiencing problems with it, be weary of your next upgrade. We weren't having issues with 7.6 but began seeing them with 8.0. (opposite of Rice I believe) I'm looking forward to the next suggested release, we try to stay off newer releases unless required for necessary support or features.

This is a recently new install and has only been up for several months, but so far the code has been stable. Hopefully not too far off topic, but has anyone experienced issues with running SSO high availability on their controllers and codes versions? In the beginning we ran it without any issues, but swapped over to the N+1 per third party recommendations. So I'm just looking for any info whether it be good or bad. Mark G.

One of those projects is the upgrade of our 5508 controllers which are currently running version 7.6.130.33. I see back in March there was a discussion regarding recommended versions of Cisco WLC code and some of the recommendation included; 8.0.121.0 and 8.1.131.X, I was looking to see if time has changed these recommendations or are these still the most stable releases. Our APs consist of models, 3500, 3600, and 702W.
