I need to configure FreeRADIUS Version 2.2.6 to retrieve LDAP security group membership, and am hoping someone here can help. In this case I have a web application that queries FreeRADIUS. FreeRADIUS then goes to the LDAP server and authenticates the user. User authentication works, but I've tried a couple of things to get the LDAP server to return security group membership with no luck. I have added and included a dictionary file with a definition of my vendor-defined attribute as follows: VENDOR Uplogix 10243 BEGIN-VENDOR Uplogix ATTRIBUTE Uplogix-User-Groups 3 string After reading through available documentation, I tried to return the groups with the following in the /erc/raddb/users file, but it doesn't work: DEFAULT Uplogix-User-Groups = Ldap-Group Should I instead be requesting the LDAP group in the post-auth section of the LDAP module? If so can I get an example of how the syntax should work for that? Thanks in advance, Adam Thompson
