mod_gridsite 2.3.4 and Apache 2.4.38 ?

[ffurano]

Hi,

trying to solve some old Apache bugs I have upgraded an apache 2.4.6 with libgridsite 2.3.4 to apache 2.4.38, and apparently mod_gridsite did not accept anymore clients coming with a VOMS proxy certificate. I downgraded Apache and it started working again.

Apparently, the module is loaded fine, the initialization log looks weird to me:
" (-1884219592)Unknown error -1884219592: mod_gridsite: mod_ssl_with_insecure_reneg = 1"
After a request, the error that I could see is:
" AH02039: Certificate Verification: Error (40): proxy certificates not allowed, please set the appropriate flag"

Are you aware of this apparent incompatibility?
Do you have any suggestion that could allow me to upgrade Apache in a CC7 machine and keep mod_gridsite working?

I had taken Apache from this repo:
https://repo.codeit.guru/packages/centos/7/x86_64

Thank you for any hint
