Hi,
it seems that you are affected by https://bugzilla.redhat.com/show_bug.cgi?id=1880149 Could you please try the workaround mentioned there?
bingo! Thanks a lot!
It is interesting behavior as my engine has no public ipv6 address (ipv6 is set to ignore in nm).
also
[root@ovirt ~]# ping6 google.com connect: Network is unreachable
but ok, problem is solved :-)
Most probably your LDAP server can be resolved to both IPv4 and IPv6 addresses and we choose a random resolved address in aaa-ldap when connecting. Enabling IPv6 by default was introduced in https://bugzilla.redhat.com/1726189 but unfortunately we have missed this scenario (engine IPv4, LDAP dual IPv4/IPv6) during testing ...

Thanks, Martin

Hi,
I just upgraded my HE to 4.4.2 but now I cannot login using my ldap
aaa
profile anymore.
We are using Novell/NetIQ E-directory (load ballanced by haproxy, probably not important...)
In 4.4.1 I was hit by removed TLSv1 (which is the newest protocol supported by our edir) from default crypto policies but I was able revert it by
update-crypto-policies --set LEGACY
after upgrade to 4.4.2 the error is
server_error: An error occurred while attempting to connect to server ldap1.slu.cz:389 <http://ldap1.slu.cz:389>: IOException(LDAPException(resultCode=91 (connect error), errorMessage='An error occurred while attempting to

but our ldap server is reachable from ovirt, I tested it via (also
ldaps
and startls variants are working)
ldapsearch -H ldap://ldap1.slu.cz <http://ldap1.slu.cz> -x -D cn=*****,ou=******,o=su -w '************' -b 'o=su'
As a workaround I tried to set plain ldap protocol in profile
cat /etc/ovirt-engine/aaa/CRO.properties
include = <rfc2307-edir.properties>
vars.server = ldap1.slu.cz <http://ldap1.slu.cz> vars.port = 389 vars.user = cn=*****,ou=******,o=su vars.password = **************
pool.default.serverset.single.server = ${global:vars.server} pool.default.serverset.single.port = ${global:vars.port} pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password}

debug with tcpdump reveals only that connection is made and there are only "bindRequest" and "bindResponse success" messages visible (with correct tcp handshake and close) and nothing more
any help would be appreciated
Cheers,
