+# MariaDB with PAM authentication via LDAP against an ActiveDirectory server
+
+This image directly derives from the official mariadb image from docker hub, (https://hub.docker.com/_/mariadb).
+
+It is built via a CI/CD pipeline on Gitlab from the repository https://gitlab.com/wolutator/mariadb-with-ldap-pam.
+
+The `libpam_ldap` package is installed and configured. Final values for the LDAP configuration are loaded at start time of the container from environment variables given on the command line.
+
+These variables are
+
+  * `LDAPURI`: LDAP URI, like `ldap://dc.yourdomain.com:389`
+  * `LDAPBASE`: Search base, like `DC=YOURDOMAIN, DC=com`
+  * `LDAPBINDDN`: DN of a user to read on the ActiveDirectory server
+  * `LDAPBINDPW`: Password of that user
+
+Start the container after creating the required volumes (see documentation of the original mariadb image) with something like this:
+
+    docker run --rm --name mariadb \
+      -e LDAPURI="ldap://dc.yourdomain.com:389" \
+      -e LDAPBASE="dc=YOURDOMAIN,dc=com" \
+      -e LDAPBINDDN="ldapbinddn" \
+      -e LDAPBINDPW="ldapbindpw" \
+      -e MYSQL_ROOT_PASSWORD=test123 \
