Hello , I think I resolved this issue. It is dig response when resolving the domain name!
CentOS-7 - bind-utils-9.11.4-16.P2.el7_8.6.x86_64; Windows AD level 2008R2; in my case dig returns answer with ;; ANSWER SECTION: mb118.local. 600 IN A 192.168.1.7 IP address returned is address of DC CentOS-8 - bind-utils-9.11.20-5.el8.x86_64; Same Domain Controller; dig returns answer without ;;ANSWER SECTION e.g. IP address of DC cannot be identified. The solution is to add directive '+nocookie', after '+tcp' in the file /usr/share/ovirt-engine-extension-aaa-ldap/setup/plugins/ovirt-engine-extension-aaa-ldap/ldap/common.py The section starts at line 144: @staticmethod def _resolver(plugin, record, what): rc, stdout, stderr = plugin.execute( args=( ( plugin.command.get('dig'), '+noall', '+answer', '+tcp', '+nocookie', what, record ) ), ) return stdout With this change execution of ovirt-engine-extension-aaa-ldap-setup completes successfully and joins fresh install of oVirt 4.4 to Active Directory. If level of AD is 2016 '+nocookie' change is not needed. Happy holydays to all of you! Stay safe! Thank you!
