Hi, I would like to know if anything related to configuration has been changed in 2.0 version when compared with 1.1.6 Iam running radiusd -C command it throws the below error. Is it a valid error or I can ignore it. /etc/raddb/users[21]: Parser error (check) for entry DEFAULT: Invalid Octet String "sales" for attribute name "ldap_primary-Ldap-Group" My users file look like this. #primary ldap group policy configuration DEFAULT ldap_primary-Ldap-Group == "sales", XYZ-Attr-4=~"1", Auth-Type:=DUAL-LDAP Thanks in advance.
