I know how it can be done with CLI command, but I try to replicate this behavior with rest-api call. Here is the CLI command I want to replicate with rest-api call :

keystone user-password-update --pass $PASS $TENANT

I try a few things, but didn't find something that work. when I run this CLI command with --debug it's look like there is a PUT made, but there is not that much information how to replicate it:

DEBUG:urllib3.connectionpool:"PUT /v2.0/users/f17c65fea3864123daf8aa1b21ad75081/OS-KSADM/password HTTP/1.1" 200 258
