Hi All, I've been setting up my College's first FreeRadius server and I've been having a hard time wrapping my brain around the config with the documentation that is available. If you'll bear with me here through this super long post, I'll go into more depth. What I'm trying to do: I want to configure FreeRadius to Authorize a user against an LDAP directory based on IF that user has the following values: *edupersonprimaryaffiliation: *STAFF AND *psadminarea*: BUSINESS - SMEAL COLLEGE _OR_ *edupersonprimaryaffiliation: *Faculty AND *psadminarea*: BUSINESS - SMEAL COLLEGE If the user's values don't match either of these two condition, they are rejected. If they match either, then they are authenticated agains a kerberos server. I've got the basic configuration working in that FreeRadius will go out to the LDAP directory (right now it just seems to check if the attribute exists but does not make a judgement on it) and then it will go out to the Kerberos server and Authenticate. I want to now add the conditions I stated above but I'm a bit lost this point. At first I thought that this was something the CheckValue module should handle, then I thought maybe it should just be a part of the filter in the LDAP module, then I thought about maybe the values need to be in the dictionary files. At this point, it became apparent that I simply don't understand how FreeRadius handles itself. It is not apparent to me how or where FreeRadius makes its decisions on conditional values. This is where I hope some of you can help. I really like FreeRadius in that it is obviously a quality product, but as it is with the documentation and my lack of Radius experience, I just can't seem to get at the last piece of this puzzle. Right now, I have the following settings (with debug output further down) radiusd.conf, LDAP module: ldap { server = "ldap.psu.edu" # identity = "cn=admin,o=My Org,c=UA" # password = mypass basedn = "dc=psu,dc=edu" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" # base_filter = "(objectclass=radiusprofile)" # set this to 'yes' to use TLS encrypted connections # to the LDAP database by using the StartTLS extended # operation. # The StartTLS operation is supposed to be used with normal # ldap connections instead of using ldaps (port 689) connections start_tls = no # tls_cacertfile = /path/to/cacert.pem # tls_cacertdir = /path/to/ca/dir/ # tls_certfile = /path/to/radius.crt # tls_keyfile = /path/to/radius.key # tls_randfile = /path/to/rnd # tls_require_cert = "demand" # default_profile = "cn=radprofile,ou=dialup,o=My Org,c=UA" # profile_attribute = "radiusProfileDn" access_attr = "psadminarea" # Mapping of RADIUS dictionary attributes to LDAP # directory attributes. dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 # # NOTICE: The password_header directive is NOT case insensitive # # password_header = "{clear}" # # Set: # password_attribute = nspmPassword # # to get the user's password from a Novell eDirectory # backend. This will work *only if* freeRADIUS is # configured to build with --with-edir option. # # # The server can usually figure this out on its own, and pull # the correct User-Password or NT-Password from the database. # # Note that NT-Passwords MUST be stored as a 32-digit hex # string, and MUST start off with "0x", such as: # # 0x000102030405060708090a0b0c0d0e0f # # Without the leading "0x", NT-Passwords will not work. # This goes for NT-Passwords stored in SQL, too. # # password_attribute = userPassword # # Un-comment the following to disable Novell eDirectory account # policy check and intruder detection.
