Breaking: #91974 - Configuration Option IPmaskMountGroups removed
See forge#91974
Description
The global configuration option
$GLOBALS has been removed. It allowed to automatically assign
groups to users visiting the TYPO3 Frontend from specific IP addresses / networks.
This is especially handy to show content only in Intranet/Extranet sites where internal members see restricted content automatically.
However, showing content based on certain contexts is usually solved with a much more flexible way through third-party extensions such as EXT:contexts. Third-party extensions allow even for automatic login based on IP-addresses, which should be used instead.
Impact
The mentioned option is automatically removed from Local
on upgrade, and not evaluated anymore.
Affected Installations
Installations having the global configuration setting set in
typo3conf/ or typo3conf/, mostly related to intranet / extranet websites.
Migration
If this functionality explicitly is required, it can be provided by a third-party extension, or a custom extension registering a AuthenticationService ("getGroupsFE") to assign the groups on a more specific approach.
