Hi,
Anyway... Nick from RedHat is on this list, so it would be a question for Nick, how 2.2.x could be pushed into the 6.x repos to replace 2.1.12 (the last official version).
the biggest issue is if there is ANY bit of 2.2.5 vanilla which breaks/incompatible with a 2.1.x install (ie current distro version) - obviously an admin of 2.1.x that got upgraded wouldnt see all the new cool features that have arrived since 2.2.0 came on-shore all those years ago (on 10 Sep 2012 !!) (in fact, looking at 2.2.5 default raddb config there appear to be a few options missing that are related to post 2.2.0 feature additions - I'll see if i've got time to push any of those) I *believe* the only different of note is that "hashsize = 0" in passwd module is NOT allowed and will break the server ...but that wasnt set to '0' by default IIRC...... but there may be some behaviour changes (ie due to bug fixes) that might affect a 2.1.x that WAS working because of fortune or some crazy workaround...those pesky value/attribute operators! :-) alan
