Is possible have 3 administrator in a WLC5508 , and each have access a configuration of the group of access-points?
WLC5508 with 30 AP.
Admin1: access configuration for 10 AP (AP1, AP2, .... AP10)
Admin2: access configuration for 10 AP (AP11, AP12,... AP20)
Admin3: access configuration for 10 AP (AP21, AP22, ... AP30)
Or is it possible with another product like WCS ou ACS?
No, you cannot setup any sort of security so that specific people can only administer specific AP's. You could use TACACS so that there would be logging of the administration tasks.
