Remove self-service from external auth


never thought to open a thread on such a topic.
We have icingaweb2 set up with external Apache Authentication. Thus I want to remove self-service from Apache authentication.

I tried the usual things as

<Location /icingaweb2/director/self-service>
   Order allow,deny
   Allow from all
   Satisfy any
   AuthType none

I already made for sure that

<Directory "/usr/share/icingaweb2">
    AllowOverride AuthConfig Limit

is set as director is not within

<Directory "/usr/share/icingaweb2/public">
    Options SymLinksIfOwnerMatch
    AllowOverride AuthConfig Limit

Any ideas? DebugLog does not really helped…

Best & Thanks,
