I doubt very much that the user - or at least the user information in the database - is actually getting corrupted. It's more likely some sort of connection error between the extension or JDBC driver and SQL Server. So, a few questions for you... - What version of Java are you using? - What version of Tomcat are you using? - What make/model/version of the MS-SQL JDBC driver are you using? - If you restart Tomcat, does the problem go away? - If you create a new user while you're able to log in, does that user account work when guacadmin does not? - Are there any system-level messages - anything in dmesg output, or /var/log/messages, etc., that indicates any other sort of problem (OOM, SELinux, etc.)? Also, if you could, could you configure the Guacamole Client for either debug or trace logging and post the output (preferably in a PasteBin or something like that, and not in the e-mail)? This can be done by creating a logback.xml file in GUACAMOLE_HOME, and you can find instructions for what that file needs to contain here: http://guacamole.apache.org/doc/gug/configuring-guacamole.html#webapp-logging -Nick
