Hi, I wanna to authenticate user by LDAP server. But I have two LDAP servers for different group of users. For example, students or staffs, each has different realm name. Students' realm name is @stud.test and staffs' realm name is @staf.test. Realm (@stud.test) must pass to LDAP server one to authenticate. And realm (@staff.test) must pass to LDAP server two to authenticate. Does freeradius support this scenario ?? And how to do it ?? Thanks. Rio
