Key: GUACAMOLE-1377

Issue Type: Bug
Reporter: Victor
Hi Team,
I try to connect our guacamole server to the percona server we have recenrly
deployed:
8.0.23-14.1 Percona XtraDB Cluster (GPL), Release rel14, Revision d3b9a1d,
WSREP version 26.4.3
and this is the error we are getting:
{code:java}
0:42:26.646 [http-nio-8080-exec-10] WARN o.a.g.e.AuthenticationProviderFacade -
The "mysql" authentication provider has encountered an internal error which
will halt the authentication 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.
10:42:26.646 [http-nio-8080-exec-10] ERROR o.a.g.rest.RESTExceptionMapper -
Unexpected internal error:
### Error querying database. Cause: java.sql.SQLException: Unknown system
variable 'query_cache_size'
### The error may exist in org/apache/guacamole/auth/jdbc/user/UserMapper.xml
### The error may involve
org.apache.guacamole.auth.jdbc.user.UserMapper.selectOne
### The error occurred while executing a query
### Cause: java.sql.SQLException: Unknown system variable
'query_cache_size'{code}
I updated the mysql-connector-java to the latest version but error seems to
still be the same
Any advice?
