Troubleshooting when working on Linux OS🔗

Excessive logging in Nginx access.log🔗

Solution🔗

To resolve the issue, you need to:

  1. In a text editor, open the Nginx configuration file:

    sudo nano /etc/nginx/nginx.conf

  2. Find the access_log directive, which by default may look like:

    access_log /var/log/nginx/access.log;

    Replace this line with:

    access_log off;

  3. Save the changes and exit the editor.

  4. Restart Nginx.

    sudo systemctl restart nginx.service

Active Directory authentication is not working🔗

Cause🔗

The Active Directory authentication issue on Ubuntu 22.04/24.04, Debian 12 and newer is due to the OS migrating to newer OpenLDAP versions. The Eocortex Server uses the LdapForNet library, which requires the older OpenLDAP 2.4.

Solution🔗

To resolve the issue, you need to install OpenLDAP 2.4. Here's how:

  1. Download and install the libldap-2.4 package:

    sudo wget http://http.us.debian.org/debian/pool/main/o/openldap/libldap-2.4-2_2.4.57+dfsg-3+deb11u1_amd64.deb

sudo apt install ./libldap-2.4-2_2.4.57+dfsg-3+deb11u1_amd64.deb

  2. After installation, delete the .deb file:

    sudo rm libldap-2.4-2_2.4.57+dfsg-3+deb11u1_amd64.deb

  3. Check that the libldap-2.4.so.2 file is now in the system directory:

    ls -la /usr/lib/x86_64-linux-gnu | grep libldap-2.4.so.2
