OpenLDAP module fails to load

[Antonio Torres]

Hello everyone,

I am the maintainer of the FreeRADIUS package for Fedora and RHEL. We
are currently trying to fix this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1983063

Apparently, it appears since this OpenLDAP commit, related to the TLS
connection start:
https://git.openldap.org/openldap/openldap/-/commit/735e1ab14

If we build the OpenLDAP package without the LDAP_USE_NON_BLOCKING_TLS
flag, the issue disappears, so it is probably related to the async
connection. I've seen there has been some work on the async LDAP
connection process, but I'm not entirely sure whether it is related,
and it is only in v4:
https://github.com/FreeRADIUS/freeradius-server/pull/4240

I'm wondering whether FreeRADIUS needs to adapt to these changes or
the issue is entirely on the OpenLDAP side. What do you think?

Thank you!
