Description

I'm currently trying to use guacamole with NLA Authentification in RDP.
It works with users who has username that contain standarts characters
(A-Z/a-z..), but when i try to connect with users who username contains "é",
"è", "Ü", "ç", "à"... characters (like "André"), i've got the error "Error
connecting to RDP Server" in syslog and i can see that the NLA
authentification failed on my server event viewer.
When i try "Andre" instead of "André", it works (AD usernames aren't case
sensitive), and if i try to connect with "André" WITHOUT NLA
Authentification, it also works.

This doesn't seems to be a FreeRDP issue, i tried NLA authentification
directly with FreeRDP (branch stable.1-1) and it works.

I activated FreeRDP Authentification logs (with cmake -DWITH_DEBUG_NLA before FreeRDP build).

Attachements :
log_guacamole.txt : connection with user "José" and NLA Authentification throught Guacamole 0-9-13 based on FreeRDP stable 1-1.
log_freerdp_only.txt : connection with user "José" and NLA Authentification throught FreeRDP stable 1-1
