Greetings,
I'm having some issues getting LDAP working on CentOS 8 with oVirt 4.4.
I would appreciate some help please.
When I run ovirt-engine-extension-aaa-ldap-setup I choose "11 - RFC-2307
Schema (Generic)" because that's what my LDAP guy said I should do. :-)
Next I select the default Yes for "Use DNS".
I select 4 for "Failover between multiple hosts".
I put in my two hosts "svr1.my.domain srv2.my.domain".
To select the protocol I type "ldaps".
To select the method to obtain the PEM I type "File".
Then the "File path". A full path to the file. Not quoted. Yes, I
checked that I typed it correct. I can copy-paste into "ls" and it's
fine with the correct read permissions and everything. (I can't copy
paste into the script but that's another issue.)
It immediately fails with:
[ ERROR ] Failed to execute stage 'Environment customization': a
byte-like object is required, not 'str'
There is a log file, here is the snippet at the point it goes wrong.

Since I wasn't getting anywhere with this, I decided to try a few
things. I copied the following files from a working 4.3 on RHEL 7
(again, this setup is CentOS8 with 4.4):
/etc/ovirt-engine/aaa/ldap.jks
/etc/ovirt-engine/aaa/ldap.properties
/etc/ovirt-engine/extensions.d/ldap-authn.properties
/etc/ovirt-engine/extensions.d/ldap-authz.properties
I verified permissions were all good (including SELinux). I restarted a
few services but wasn't getting anything at all of value telling me what
was wrong...so I rebooted. That did the trick! Now I get an error,
though nothing of use is turning up from the internet searches.
# ovirt-engine-extensions-tool info list-extensions

SEVERE: Extension 'ldap-authn.properties' load failed (ignored): Error

loading 'ldap-authz': The module 'org.ovirt.engine-extensions.aaa.ldap'

I do have these packages installed:
ovirt-engine-extensions-aaa-ldap
ovirt-engine-extensions-aaa-ldap-setup
Any thoughts on what went wrong?
Thanks!
