Hello experts!
I have this error message "NAS Duplicated authentication attempt" in the ACS reports. Where is this error coming from.
Following is the setup.
Server: Windows 2000, SP3, Q313664_W2K_SP4_X86_EN.exe, ACS 3.1, CA all in one server.
AP: Aironet 1200
Client: Windows XP SP 2
If I try by mac alone, no problem i can get through. But if i try EAP or to authenticate the user, i get that error message.
How do I checked in the client that it is using the certificate.
I've configured the external database as Windows 2000 Database and chose the domain. But still I can't authenticate. I don't even see any log events on Windows about the user authenticating.
Anyone can help me, I'd appreciate it very much.
Regards,
Neil
