If a user name contains a white space then using the UMC quota module becomes impossible. A Python error+backtrace is printed instead:

I've traced back the issue to /usr/lib/pymodules/python2.7/univention/management/console/modules/quota/tools.py def "repquota_parse". The regular expression used for matching the output of "repquota" starts with this: '(?P<user>[^ ]*) *[-+]+…' This explicitly prohibits spaces from being part of the user name.

A quick and dirty fix might be to allow white spaces within the user name capture and to require at least one white space to be present afterwards, e.g. like this: '(?P<user>.+?) +[-+]+…'

The theoretical problem with this approach is that user names that end with a white space will still not work.

The proper fix would be to let repquota report user/group IDs instead of names (by using its "-n" option) and to translate those into user names using appropriate API calls.
