Support With mod_auth_cas Issue

[Infosys Raleigh]

Hello,

We are trying to set up a CAS Client on an ec2, running ubuntu 16LTS, using the mod_auth_cas project. we have gotten everything downloaded, complied, built and installed as per the README but when we try to start with:

 

sudo systemctl enable apache2 

we get:

 

undefined symbol: SSL_CTX_set_verify_depth

from the mod_auth_cas.so 

We are not sure what information would be useful, so feel free to ask for anything you might need and we will try to provide.

This reeks of some mismatch with your OpenSSL libraries.

Are you using the system wide OpenSSL and associated SSL lib's or are
you rolling your own OpenSSL as well.

If the latter be sure that pkg-config and other ./configure directives
are actually using your own libraries versus the system wide ones.

Also check that the Apache your using is using the same OpenSSL as
you're using to make your .so module.

[Infosys Raleigh]

we are using a system-wide OpenSSL

and only one is installed

apt-cache policy openssl

returns: 
Installed: 1.0.2g-1ubuntu4.15

We found a solution. We found an apt package that we could install instead of rolling our own.
