The problem is not to link against it in general, but to link a *GPL
program* against it.

That's the case for mod-auth_cas, which is GPL V3.

More details about the incompatibilities here :

So yes, openssl is in Debian, so one may build mod-auth_cas on his/her
machine, but redistribution of a package may not be possible by
Debian :(

Now, I was told there seems to be a possible solution, in adding an
exception to the GNU GPL if the author wishes so.

Thanks for your comments.

Best regards,
