Below the solution. Resolved By "Alon Bar-Lev" <alonbl(a)redhat.com&gt; 1. install ovirt-engine-extension-aaa-ldap, it is available in ovirt-3.5-snapshots repository. 2. create /etc/ovirt-engine/extensions.d/din.intranet-authz.properties ovirt.engine.extension.name = din-intranet-authz ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthzExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authz config.profile.file.1 = /etc/ovirt-engine/aaa/din.intranet.properties 3. create /etc/ovirt-engine/extensions.d/din.intranet-authn.properties ovirt.engine.extension.name = din-intranet-authn ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthnExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authn ovirt.engine.aaa.authn.profile.name = din.intranet ovirt.engine.aaa.authn.authz.plugin = din-intranet-authz config.profile.file.1 = /etc/ovirt-engine/aaa/din.intranet.properties 4. create /etc/ovirt-engine/aaa/din.intranet.properties include = <ipa.properties> vars.user = uid=admin,cn=users,cn=accounts,dc=din,dc=intranet vars.password = 123456 vars.server = ipa1.din.intranet pool.default.serverset.single.server = ${global:vars.server} pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password} 5. restart engine.
