Hi Nick,
We have already configured Debug in logback.xml as below <configuration> <!-- Default appender --> <appender name="GUAC-DEFAULT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <!-- Log at DEBUG level --> <root level="debug"> <appender-ref ref="GUAC-DEBUG" /> </root> </configuration> Also we are using /usr/share/tomcat/.guacamole/guacamole.properties as the guacamole directory and below is a Snap of Gucamole Properties file guacd-hostname: localhost guacd-port: 4822 auth-provider: net.sourceforge.guacamole.net.auth.ldap.LDAPAuthenticationProvider auth-provider: net.sourceforge.guacamole.net.auth.mysql.MySQLAuthenticationProvider mysql-hostname: 10.19.1.25 mysql-port: 3306 mysql-database: guacamole mysql-username: guacadmin mysql-password: *********************** mysql-default-max-connections-per-user: 5 mysql-default-max-group-connections-per-user: 5 # LDAP properties ldap-hostname: ldaps.glbl.bnv.com ldap-port: 636 ldap-encryption-method: ssl ldap-search-bind-dn: CN=User,OU=“Service Accounts”,OU=Security,DC=glbl,DC=bnv,DC=com ldap-search-bind-password: ******************** ldap-user-base-dn: DC=glbl,DC=bnv,DC=com ldap-username-attribute: sAMAccountName ldap-user-search-filter: (memberOf=CN=GLBL PROCESS MODELLING,OU=Common,OU=Groups,DC=glbl,DC=bnv,DC=com) there is a space between service and accounts so used double quotes.

Also checked the catlina.out as well no logs. Checked in all possible locations but there are no authentication/failure logs. Next step would be to enable debug logging in Guacamole: http://guacamole.apache.org/doc/gug/configuring-guacamole.html#webapp-logging It's also important to know where your configuration is actually stored - you mentioned ".guacamole"; however, the default location has been /etc/guacamole for a couple of versions, so make sure you're aware of what location is actually in use. This could also contribute to errors - if the configuration is not in the correct location, it may not be reading the configuration at all. -Nick "This e-mail and any attachments to it (the "Communication") is, unless otherwise stated, confidential, may contain copyright material and is for the use only of the intended recipient.
