A customer created service user with login/email using IDN domain. POA task to register of the user (mailbox) in Open-Xchange fails with error message 'Illegal chars: " "'.


Open-Xchange configuration has particular settings for login and mapping validation, by default IDN symbols are not allowed in login and mapping.


Perform the following changes on Open-Xchange server:

1. Edit the /opt/open-xchange/etc/admindaemon/ file - disable the CHECK_USER_UID_FOR_NOT_ALLOWED_CHARS option:
2. Edit the /opt/open-xchange/etc/admindaemon/plugin/ file - change the CHECK_CONTEXT_LOGIN_MAPPING_REGEXP option to allow all symbols:
3. Restart Open-Xchange services:
 # /etc/init.d/open-xchange-groupware restart
# /etc/init.d/open-xchange-admin restart
