"LDAP_SYNC_INFO" is not exported by the Net::LDAP::Constant module

Hello,

I found a thread last year (12 Feb, 29 June 2009) about this same
symptom I am experimenting.
The thread didn't have a clear conclusion.

I.e. I get such errors in my nightly build logs, driven by a perl
script which uses LDAP.
It seems this is intermittent: most builds succeed, and I do not know
what is special about those which fail with this error.
Also, trying from the command line (as Graham instructed) works fine,
as for previous posters.
It looks like a resource exhaustion issue!?

Was a solution ever found to this issue?

Thanks,
Marc
