Add LDAP proxying script (for development purposes)

proxy_ldap.sh

+#!/bin/sh
+
+# Add an entry to the hosts file so that any request to ldap2.cl.uni-heidelberg.de will be redirected
+# to localhost, and then use SSH to forward any requests to localhost (port 636) to ldap2.cl.uni-heidelberg.de.
+#
+# Expected usage is within the container:
+#
+#   sudo docker compose -f docker-compose.dev.yml up
+#   sudo docker exec -it portal-app-1 bash
+#   ./proxy_ldap.sh mustermann
+#
+# Replace "mustermann" with your ICL username.
+
+echo "127.0.0.1 ldap2.cl.uni-heidelberg.de" >> /etc/hosts
+ssh "$1@last.cl.uni-heidelberg.de" -L 636:ldap2:636
