Breaking: #91974 - Configuration Option IPmaskMountGroups removed¶
See Issue #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, are 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 never evaluated anymore.
Installations having the global configuration setting set in
typo3conf/AdditionalConfiguration.php, mostly related to intranet / extranet websites.
If this functionality explicitly is required, it can be overcome with a third-party extension, or a custom extension registering a AuthenticationService (“getGroupsFE”) to assign the groups on a more specific approach.
