Nick Couchman commented on GUACAMOLE-1081:
------------------------------------------
[~kangaroo22]: I figured out what's going on with this - turns out the modifier
is getting canonicalized along with the rest of the token, so:
{code}
${GUAC_USERNAME:lower}
{code}
becomes:
{code}
${GAUC_USERNAME:LOWER}
{code}
and the code didn't taken that into account. I've submitted the pull request
so that it pays attention to and both "lower" and "LOWER" should behave the
same.

> Key: GUACAMOLE-1081
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1081
> Project: Guacamole
> Issue Type: New Feature
> Components: Documentation, guacamole-ext
> Reporter: Jason Keltz
> Assignee: Nick Couchman
> Priority: Minor
> Fix For: 1.3.0
>
>
> When the user logs into Guac with parts of their username in uppercase, the
> login to Guac is successful, but then subsequent login to Linux systems fails
> because the username is case sensitive. It would be useful to have an option
> in Guacamole to convert usernames to lowercase or uppercase before passing on
> to the systems.
> One possible suggestion from Nick on the mailing list was something like this:
>
> ${GUAC_USERNAME} - Pass through as entered
> ${GUAC_USERNAME:lower} - Convert string to lower-case
> ${GUAC_USERNAME:upper} - Convert string to upper-case
>
> This would work very well.
> I would be likewise happy with a solution that let me set a default somewhere
> (in my case, all lowercase).
