Breaking: #91974 - Configuration Option IPmaskMountGroups removed

See forge#91974


The global configuration option $GLOBALS['TYPO3_CONF_VARS']['FE'][IPmaskMountGroups] 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.


The mentioned option is automatically removed from LocalConfiguration.php on upgrade, and not evaluated anymore.

Affected Installations

Installations having the global configuration setting set in typo3conf/LocalConfiguration.php or typo3conf/AdditionalConfiguration.php, mostly related to intranet / extranet websites.


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.
