Here is a simple script to list all tenants belonging an user:
#!/bin/bash
echo -n "Username : " ; read usercheck
for userid in $(keystone user-list | grep -w $usercheck | awk '{print$2}')
do
for tenant in $(keystone tenant-list | awk 'NR>3 && /^|/ {print$2}')
do
for tenantid in $(keystone user-role-list --user $userid --tenant $tenant | awk 'NR>3 && /^|/ {print$8}')
do
keystone tenant-list | grep $tenantid | awk '{print$4}'
done
done
done
Also you can run all in a simple cmd line
echo -n "user name "; read usercheck; for userid in $(keystone user-list | grep $usercheck | awk '{print$2}'); do echo $userid | for tenant in $(keystone tenant-list | awk 'NR>3 && /^|/ {print$2}'); do echo $tenant | for tenantid in $(keystone user-role-list --user $userid --tenant $tenant | awk 'NR>3 && /^|/ {print$8}'); do keystone tenant-list | grep $tenantid | awk '{print$4}'; done ; done ; done
If you are a developer, probably you need to list all tenants in a HTTP request, for this purpose you can use the REST API to the port 5000 of keystone
