Hi everyone,
I'm need to all help on the problem as description on subject. Specific as following:
I have 2 WLC 7010 OS 8.3 both running Standalone (10.26.3.10) and Standby (10.26.3.11) with VRRP IP (10.26.3.12). The synchronization between the two devices is working fine.
I am configuring authentication with RADIUS server 2016 (10.26.14.3). Authentication from WLC with CLI "aaa test-server mschapv2 servername username password" is ok. But when I authenticate from users, I get the message "try later". I also received a "server rejected" message when the CLI "show auth-tracebuf mac MAC-Client" message from the user received a "try later" message, and "authmgr [3514]: <522275> <3514> <WARN> | authmgr User Authentication failed. Username = abc userip = 0.0.0.0 usermac = f0: 79: e8: a2: 2b: db authmethod = 802.1x servername = TD-RADIUS-01 serverip = 10.26.14.3 apname = AP-01 bssid = b4 : 5d: 50: 0d: b4: 21".
The important thing I want to say here is that when I first configure everything works fine (Windows laptop, Android, iPhone). But about 20 minutes later, users can't authenticate and receive a "try later" message.
Look forward to the help of everyone.
Thank you everyone.
