I configured a WLC to integrate with LDAP, it is working just fine when I use only one Active Directory server but I have other users in other Active Directory Server. when I enable both servers and some users try to login with the second server WLC breakes for a little while, it is unable to configuring the equipment nor telnet it during that time and the users can not be authenticated anymore, I have to disable both servers and then enable just one of them in order users can login again. I also saw this behavior when more than 4 users try to connect to the same AP at a time.
does anybody know why this is happening and how to avoid it?
thank you very much for your help
Yeah, that leads me to believe that your RADIUS isn't properly configured. I should have made it more clear, but in order to do 802.1x, you have to have either an IAS or ACS which extends your AD (or LDAP I suppose, but I'm not certain it's supported). You can't just point your controller to your AD, it simply won't work.
