Unable to login Guacamole 1.5.1 using MD5 method from AlmaLinux 9.1 server.

[Fredtx]

This is a new setup. I followed this guide I found online Use Guacamole on Centos 8

Linux Distro- AlmaLinux 9.1
Guacamole version: 1.5.1

I'm able to login Guacamole webui when I specify a plain text file in the /etc/guacamole/user-mapping.xml file, but not md5 encoding. I create the hash using echo -n password | openssl md5

Apache Tomcat logs say: "POST /guacamole/api/tokens HTTP/1.1" 403 267".

Update: Issue is resolved.
