Location and pupose of this tmp file

[jadeas]

I am trying to recover a phpldapadmin instance embedded in our internal website. Currently, starting the app returns a warning:
E_WARNING: Unknown: open(/tmp/sess_5srr0j98g6glnuov2bdmligo07, O_RDWR) failed: No such file or directory (2)

Leads me to believe that a tmp directory somewhere has filled up, disappeared, or lost permission to create a files. Knowing that php can have its own /tmp directory, where is a good place to confirm the actual directory being used to troubleshoot this file creation issue?

You are probably looking for https://www.php.net/manual/en/session.configuration.php#ini.session.save-path

Yes, a good step forward, thank you for that link. I'm researching now where plaConfig comes into the picture and if it creates a custom path for the session data.

Digging deeper I am still not sure of where the /tmp should be located. Where does phpldapadmin store the SESSION data (files)? I ma not seeing them in /tmp or finding an alternate path. The session seems to be creating, I do see a cookie with the session uid but I still get this error.

Warning: Unknown: open(/tmp/sess_0ilrner3sa5omqo5dsh6ovn9d1, O_RDWR) failed: No such file or directory (2) in Unknown on line 0
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct () in Unknown on line 0

The folder is located where the php ini config said it is located.
To find the file that defines the value run php --ini or a better alternative is to have a test page that has:

<?php
phpinfo();

It is not PLA that manages the storing of the files or their location, only PHP itself :)

Yesterday I injected phpinfo() into the opening page (/htdocs/index.php). This showed the session.path as ‘no value’ so I assume it would be /tmp by default. The folder is wide open so why I get this error on the opening page is still a mystery. “E_WARNING: Unknown: open(/tmp/sess_lag45jer6fjbap1v09329jj8c2, O_RDWR) failed: No such file or directory (2)” Is it possible that httpd, which is using an alias to point at phpldamadmin/htdoc is creating the issue with writing the session file ?

You should try to set another value for session.path in the PHP ini file, it may be easier than trying to debug this weird issue
