Have you checked your MySQL configuration to make sure that SSL is
enabled? You can also try setting "mysql-ssl-mode" in your
guacamole.properties file to "disabled" and see if that helps.

Yes, you could also try updating the MySQL Connector/J - but I'd try
the SSL settings, first.

2023-07-17 Thread Xuo 

Hi,

After more than 3 weeks without any internet connection (except through 
my phone), I can now try to debug again my issue.
To summarize, you were right. If I keep only one single extension, the 
error disappears.

Now, I've got another one.

journalctl --since 09:17
juil. 15 09:17:47 ordi4 server[1272619]: 09:17:47.453

provider has encountered an internal error which will halt the

process. If this is unexpected or you are the developer of this 
authentication provider, you may wish to enable debug-level logging. If 
this is expected and
you wish to ignore such failures in the future, please set 
"skip-if-unavailable: mysql" within your guacamole.properties.

to connect with ssl, but ssl not enabled in the server


And some more lines.
I've search during the whole week-end without success.
If you have any idea, I'll be glad to test it.

mysql-connector-j.jar corresponds to the version of MariaDB connector/J3.1.4

mysql-connector-java.jar comes fromthe following mageia package : 
mysql-connector-java-8.0.22-2.mga8



*While I am writing this email, I wonder if I should not try to install 
a more recent version of **mysql-connector-java 
(**mysql-connector-j-8.0.33 is the latest one) instead of the one coming

mysql-hostname: localhost

Some extensions (looking at you, TOTP) will make Tomcat crash with 
this exact error if multiple versions are loaded.




We should add an additional sanity check to warn if this condition is 
detected, but FYI:


The reason multiple copies of the same extension cannot be loaded at 
the same time is their namespaces will collide. Every extension 
defines a unique namespace to isolate itself from others. If that 
namespace isn't actually unique, then resources/endpoints declared by 
those extensions will have conflicting paths, causing webapp startup 
to fail.

Hello,

Yes, I have multiple extensions versions, at least 1.4 and 1.5.2 (totp 
and probably another one). I'll check tomorrow hopefully.

You'll probably need to enable additional debugging in the Guacamole

I think the error you're seeing indicates it's more basic than this -
this would be the Apache httpd configuration for the proxying
Guacamole, but it seems like Tomcat is failing to load it for some
reason.
