Hello. I'm attempting to bring up a FreeRadius-2.1.1 rig that auths against AD. NTLM authentication seems to work well, but LDAP authorisation appears to hit a problem when extracting the DN: rlm_ldap: Entering ldap_groupcmp() [files] expand: ou=staff,dc=uk,dc=mydomain,dc=com -> ou=staff,dc=uk,dc=mydomain,dc=com [files] expand: (sAMAccountName=%{mschap:User-Name}) -> (sAMAccountName=jhreed) rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in ou=staff,dc=uk,dc=mydomain,dc=com, with filter (sAMAccountName=jhreed) rlm_ldap: ldap_release_conn: Release Id: 0 [files] expand: (|(&(objectClass=GroupOfNames)(member=%{check:Ldap-UserDn}))(&(objectClass=G roupOfUniqueNames)(uniquemember=%{check:Ldap-UserDn}))) -> (|(&(objectClass=GroupOfNames)(member=CN\3dJohn Hawkes-Reed\2cOU\3dIT\2cOU\3dStaff\2cDC\3duk\2cDC\3dmydomain\2cDC\3dcom))(&( objectClass=GroupOfUniqueNames)(uniquemember=CN\3dJohn Hawkes-Reed\2cOU\3dIT\2cOU\3dStaff\2cDC\3duk\2cDC\3dmydomain\2cDC\3dcom))) rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in cn=vpn-users,ou=Security Groups,ou=Groups,dc=uk,dc=mydomain,dc=com, with filter (|(&(objectClass=GroupOfNames)(member=CN\3dJohn Hawkes-Reed\2cOU\3dIT\2cOU\3dStaff\2cDC\3duk\2cDC\3dmydomain\2cDC\3dcom))(&( objectClass=GroupOfUniqueNames)(uniquemember=CN\3dJohn Hawkes-Reed\2cOU\3dIT\2cOU\3dStaff\2cDC\3duk\2cDC\3dmydomain\2cDC\3dcom))) rlm_ldap: object not found or got ambiguous search result rlm_ldap: ldap_release_conn: Release Id: 0 rlm_ldap::ldap_groupcmp: Group cn=vpn-users,ou=Security Groups,ou=Groups,dc=uk,dc=mydomain,dc=com not found or user is not a member. Running ldapsearch against AD shows the following: # vpn-users, Security Groups, Groups, uk.mydomain.com dn: CN=vpn-users,OU=Security Groups,OU=Groups,DC=uk,DC=mydomain,DC= com objectClass: top objectClass: group cn: vpn-users member: CN=John Hawkes-Reed,OU=IT,OU=Staff,DC=uk,DC=mydomain,DC=com distinguishedName: CN=vpn-users,OU=Security Groups,OU=Groups,DC=uk,DC=mydomain,DC=com I can find a similar bug mentioned in the archives, but that appeared to be an older version of the code. Hopefully that's enough debug to enable someone to point me in the right direction.
