[ovirt-users] Info about AD integration and Root CA

Hello, in docs for 4.2 RHV (I think it applies to oVirt 4.2 too) for attaching to AD there is the statement " To set up secure connection between the LDAP server and the Manager, ensure a PEM- encoded CA certificate has been prepared. See Section D.2, “Setting Up Encrypted Communication between the Manager and an LDAP Server” for more information. " and in Appendix " To set up encrypted communication between the Red Hat Virtualization Manager and an LDAP server, obtain the root CA certificate of the LDAP server. . . " and in readme file referred in the Appendix (/usr/share/doc/ovirt-engine-extension-aaa-ldap-1.3.8/README) there is the command: " Active Directory Windows: > certutil -ca.cert myrootca.der Linux: $ openssl -in myrootca.der -inform DER -out myrootca.pem " In my case on Windows DC (that is a Windows 2012 R2 server with "Domain functional level: Windows Server 2003") I get this error: C:\Users\Administrator.MYDOMAIN>certutil -ca.cert mydomain.der CertUtil: The system cannot find the file specified. C:\Users\Administrator.MYDOMAIN> What does it mean exactly? Thanks in advance, Gianluca
