Hi,
I am currently trying to create a new auth system for our WPA 802.1x
WiFi network.
Thus far I have the server authenticating using PEAP(MSCHAPv2) against a
users file containing a simple test user/pass pair.
What I would now like to do is use MySQL to contain user data such as
the VLAN to be assigned to that user and which LDAP server their account
Assuming you know how to make the VLAN assignment work at all, then this
is trivial.
Assigning a completely dynamic LDAP server might be a little more tricky.
If you know what set of LDAP server(s) you want to use in advance, then
you could do this:
modules {
ldap ldap1 {
# config here
}
ldap ldap2 {
# config here
}
}
authorize {
preprocess
mysql
mschap
eap
Autz-Type Ldap1 {
ldap1
}
Autz-Type Ldap2 {
ldap2
}
}
The "mysql" module/tables will need to set Autz-Type on the requests, at
which point the authorize stanza will be run *again* executing the
conditional sections.
...however making this work correctly in the presence of eap/ms-chapv2
will not be straightforward, and in any event you have the other issue...
exists on, then use LDAP to verify the credentials.
The only "verification" LDAP can do of credentials is to proxy PAP
requests to LDAP simple binds. You cannot check MS-CHAP "against" an
LDAP server.
However using LDAP as a database, as it was intendended, then *if* the
LDAP server contains either plaintext password or the NT/LM hashes, the
radius server can read them, and the ldap module is configured to get
them from LDAP, then FreeRadius can perform the MS-CHAP inside itself.
The idea being that a PEAP request comes in, tunnel gets built etc, the
user gets looked up in the MySQL database, the credentials are then
authenticated against the correct LDAP (or RADIUS) server, then on
success an access-accept along with the user's VLAN is passed back to
the NAS.
This seems extremely hard work. Why would you use both MySQL and LDAP?
The question is, is it possible for PEAP(MSCHAPv2) and LDAP with MySQL
to interact in this way?
Your question is not precise enough for me to be sure exactly what you want.
