[keycloak-user] NullPointerException when attempting to remove group

[Tiemen Ruiten]

Hello,

I'm getting the following error when I attempt to delete a group that has
been imported from a FreeIPA LDAP User Federation through a
group-ldap-mapper:

In fact, I can not delete any groups anymore. There are two LDAP User
Federations setup, one to an Active Directory, one to the aforementioned
FreeIPA instance.  Both have group mappers setup and some of the group
names clash unfortunately, that's why I wanted to delete some groups and
redo the import. What can I do?
