Hello, I've been trying to configure openldap for use with radius. I'm running a RedHat ES 4 server with the following rpm's installed: openldap-2.2.13-3 freeradius-1.0.1-3.RHEL4 I've been following the instructions in ldap_howto.txt, and I created the schema.ldif file exactly as outlined in the doc. But when I run the ldapadd command it gives the following error: [root@myserver]# ldapadd -f schema.ldif -x -D "cn=root,dc=mydomain,dc=com" -w secret adding new entry "dc=mydomain,dc=com" adding new entry "ou=radius,dc=mydomain,dc=com" adding new entry "ou=profiles,ou=radius,dc=mydomain,dc=com" adding new entry "ou=users,ou=radius,dc=mydomain,dc=com" adding new entry "ou=admins,ou=radius,dc=mydomain,dc=com" adding new entry "uid=dial,ou=profiles,ou=radius,dc=mydomain,dc=com" ldap_add: Object class violation (65) additional info: no structural object class provided I do have the include statement for "RADIUS-LDAPv3.schema" configured in my slapd.conf, and I already verified that it is readable by the user ldap (and that the path is correct). Here is the entry ldapadd is erroring on: dn: uid=dial,ou=profiles,ou=radius,dc=mydomain,dc=com objectclass: radiusprofile uid: dial radiusServiceType: Framed-User radiusFramedProtocol: PPP radiusFramedIPNetmask: 255.255.255.0 radiusFramedRouting: None I've found other posts with users having the same issue, but I haven't found one detailing the resolution. I've checked to ensure that there are no extra spaces at the end of the lines. The issue is that uid is not part of the radiusprofile. So if you are using uid as your dn you would need to add another object class that requires uid and is structural. I guess the posix objectclass will have the uid attribute as a default one so you could use that IE you could use. dn: cn=doolin,ou=profiles,o=radius,dc=radiowave,dc=net cn: doolin objectClass: radiusprofile objectClass: organizationalRole objectClass: top radiusHuntgroupName: internet radiusGroupName: doolin conversly you can use any of the radiusprole attributes as the dn name if you don't want to add a new object class IE dn: radiusServiceType=dial,ou=profiles,ou=radius,dc=mydomain,dc=com objectclass: radiusprofile uid: dial radiusServiceType: Framed-User radiusFramedProtocol: PPP radiusFramedIPNetmask: 255.255.255.0 radiusFramedRouting: None - List info/subscribe/unsubscribe?
