SAML null pointer exception in docker
I'm trying to setup Guacamole with SAML for SSO. But the extension (1.4.0)
gives an unhandled error and prevents guacamole from functioning.
I have tried with various combinations of the SAML variables.
- Providing only the metadata and callback url,
- Providing all values listed in the docs
- Saml strict on/off
Nothing has worked so far.
Here's my setup
```
version: '3.3'
services:
guacamole:
container_name: guacamole
image: guacamole/guacamole:1.4.0
restart: unless-stopped
environment:
GUACD_HOSTNAME: 'guacd'

I copied it from /opt/guacamole in the container into my data directory.

Re: SAML null pointer exception in docker
Posted by Michael Jumper <mj...@apache.org>.
Is this a build of the SAML extension from git master and not the 1.4.0
release? The following line:
org.apache.guacamole.auth.saml.conf.ConfigurationService.getSamlSettings(ConfigurationService.java:327)
does not refer to an actual statement in the source that's part of 1.4.0.
It does refer to a statement in the development version of the source in
git, in which case the NPE would suggest that the Environment is not being
injected by Guice, perhaps a regression due to the recent dependency
updates.
