Cache path is not writable - CentralAuth plugin

[Sarfaraz]

Good Morning

Hope all is well, sorry if this is in the incorrect section.

I made a Multi instance server with omeka classic instances at the moment i two instance on the server running the following :

1. Centos 7
2. Php71
3. Apache
4. https://github.com/BGSU-LITS/omeka-plugin-CentralAuth

• Instance 1 works fine with the CentralAuth plugin and instance 2 does not , everything looks identical been trying everything for the last couple days with no success.

• Tried version 1.5 and 1.4 of the Plugin

• Selinux is off

• tried giving it full access rights

• When i disable the plugin the server works but not when enabled

Hello Sarfaraz, I’m the author of the CentralAuth plugin. Sorry for not getting back to you sooner, I only keep up with this forum once a week or so.

It looks like the package that the plugin uses to handle CAS creates temporary files to store session details at /tmp/simpleCAS_map_ followed by a hash. That hash appears to be based on the domain and path from session_get_cookie_params(). If the domain isn’t specified, it uses the SERVER_NAME.

Are your two installations on different domains? If so, I’m guessing that however that is set up is not changing the SERVER_NAME between the two. Otherwise, maybe something is set up oddly with your session settings.

You could also try deleting anything that begins with: /tmp/simpleCAS_map_
