Problem With Jansonn Module integration

[Leeladitya]

Hello, I am new to OPA, I am trying to integrate OPA with linux PAM, for sudo and ssh authorization, but the tutorial covers only for docker version, but i am trying to install on standalone server. I have followed the instructions from https://github.com/open-policy-agent/contrib/blob/master/pam_opa/pam/README.md, but there is problem with the jansson library module (i can't find the module to copy it to PAM module) and its very difficult to follow, can anyone help me with installing the OPA-PAM for standalone, UBUNTU server. Thanks

You can likely follow similar instructions to configure your system and build the library as what the docker image uses:

https://github.com/open-policy-agent/contrib/blob/master/pam_opa/docker/pam-builder.dockerfile

Specific to the jansson library see:

contrib/pam_opa/docker/pam-builder.dockerfile

 # Fetch and install the JSON library. 
 # Source is at: https://github.com/akheron/jansson 
 RUN wget http://www.digip.org/jansson/releases/jansson-2.11.tar.gz && \ 
     tar -xvf jansson-2.11.tar.gz && \ 
     cd jansson-2.11 && \ 
     ./configure --prefix=/usr && \ 
     make && \ 
     make check && \ 
     make install 
  
 # Archive the JSON library contents for installation in the running container. 
 RUN cd /usr/lib && \ 
     tar -cf jansson_lib libjansson* && \ 
     mv jansson_lib /
