Check_MK (or OMD) and access to network topology

After creating a new user, assigning it Administrator rights, and logging in to Check_MK, I received an error stating that there was no access to the network topology.

This resolved it:

1) SSH to the Linux server running Check_MK

2) Change directory to the Nagvis folder:
cd /omd/sites/[YOUR SITE NAME HERE]/etc/nagvis

3) Create a new file called "nagvis-make-admin.sh":
sudo nano nagvis-make-admin.sh

4) Paste this into the new file and save it:

#!/bin/bash

if [ ! -f auth.db ]; then
    echo "auth.db not found. Please make sure you execute this script in the etc/ directory of NagVis."
    exit 1
fi

if ! which sqlite3 >/dev/null 2>&1; then
    echo "Unable to find the sqlite3 binary in PATH. You need to install it to use this script."
    exit 1
fi

USER=$1

if [ -z "$USER" ]; then
    echo "No username given. Please specify the username of an existing user as argument."
    exit 1
fi

USER_ID=$(sqlite3 auth.db "SELECT userId FROM users WHERE name='$USER';")

if [ -z "$USER_ID" ]; then
    echo "User does not exist in sqlite database."
    exit 1
fi

RID=$(sqlite3 auth.db "SELECT roleId FROM roles WHERE name='Administrators';")

if [ -z "$RID" ]; then
    echo "Could not find the Administrators roles. Did you remove it?"
    exit 1
fi

echo $USER_ID
echo $RID

if [ $(sqlite3 auth.db "SELECT count(*) FROM users2roles WHERE userId=$USER_ID and roleId=$RID") = "1" ]; then
    echo "The user $USER is already Administrator. Nothing to do."
    exit 0
fi

echo -n "Adding Administrators role to user $USER..."
if sqlite3 auth.db "INSERT INTO users2roles (userId, roleId) VALUES ($USER_ID, $RID)"; then
    echo "done."
    exit 0
else
    echo "ERROR!"
    exit 1
fi

5) Make the new file executable:
sudo chmod +x nagvis-make-admin.sh

6) Install "sqlite3":
sudo apt-get install sqlite3

7) Make the new Check_MK-user a Nagvis admin:
./nagvis-make-admin.sh [YOUR USERNAME HERE]
