To preface, my knowledge of perl extends to, it exists. However, I am dealing with a script that broke, after an os upgrade. The person who wrote the script, is no longer around. It is also the only server with perl script left.
I have an old rhel 6.10 server, extended support ends in a few months. I can easily upgrade the server, no problem. The issue arises with 1 script. All the other cgi scripts work fine, but 1.
It is a script that checks for ldap users. I've tried changing the shebang to the new version of perl, after the os upgrade, 5.26.3. It was 5.10.x. I've checked permissions.
there are a number of files, in /usr/share/perl5. I assume that this ldap search, triggers 1 of these .pm files. But I don't know how to check and see if this is the case, or which .pm it might be.
I am not even sure what what else I can provide, that would be helpful.
Any ideas are welcome. If more info is needed, let me know, and I'll try to get it. I might have to sanitize sensitive parts, or course.

Thank you
