Univention Bugzilla – Bug 31728
Provide also wpad.dat
Last modified: 2017-03-21 12:35:55 CET
ucs-school-webproxy ships a proxy.pac configuration file. This is one of the two alternatives. In addition the file /var/www/wpad.dat should also be created. Especially when add the wpad DNS alias to one server, all webbrowsers try to access wpad.dat instead of proxy.pac.
This is not as easy as it looks like. According to http://de.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol the client tries to fetch the settings from (in that order): http://wpad.department.branch.example.com/wpad.dat http://wpad.branch.example.com/wpad.dat http://wpad.example.com/wpad.dat In multi server environments the school dc has to be used as proxy server. So the DNS alias "wpad.department.branch.example.com" (or any shorter version - see above) has to point to the local school dc which is providing the wpad.dat for the local environment. So there is currently no generic solution possible without modifying the local DNS settings in school dc's LDAP directory.

It is possible to overwrite the DNS alias via UCR in a S4 setup.
We should create a symlink from wpad.dat to proxy.pac. This way the admin may simply create an alias for the school server in DNS.
