I have this architecture for web-auth:
2 WLC4402 in failover with release 5.0.148, ACS 4.1 like AAA server and a SUN like LDAP server.
Someone knows wich is the right configuration on the WLC for the web-auth with LDAP (the guide 5.0 doesn't work).
I change that configuration but only one WLC works.
Thanks at all.
