Can you connect to the Hosted Engine and run 'setenforce 0' to verify that it's SELINUX ? Most probably the certificate(s) should be in '/etc/pki/ovirt-engine/certs/' .

The Insecure method with plain text password saved in /etc/ovirt-engine/aaa/uat.xxxx.com.properties works fine. I am using ovirt-engine-extension-aaa-ldap-setup utility However this is a hard coding method and insecure way. Hence I wanted to use starttls with PEM encoded certificate file. I obtained a root and intermediate CA from the Ad server and used with starttls I used below inputs for configuring AD auth with tool "ovirt-engine-extension-aaa-ldap-setup" Available LDAP implementations: 3 - Active Directory Please select: 3 Please enter Active Directory Forest name: uat.xxxx.com Please select protocol to use (startTLS, ldaps, plain) [startTLS]: startTLS Please select method to obtain PEM encoded CA certificate (File, URL, Inline, System, Insecure): file File path: /tmp/rootca.pem Enter search user DN (for example uid=username,dc=example,dc=com or leave empty for anonymous): myself(a)uat.xxxx.com Enter search user password: Are you going to use Single Sign-On for Virtual Machines (Yes, No) [Yes]: No Please specify profile name that will be visible to users [uat.xxxx.com]: Please provide credentials to test login flow: Enter user name: myself(a)uat.xxxx.com Enter user password: But I am facing error.

What could be the reason for "No trusted certificate found" error? 2.
