+# Ausführen
+
+Um die Anwendung lokal auszuführen, können die folgenden Befehle verwendet werden.
+
+```
+export GOPATH=/tmp
+source bootstrap.sh
+authelia-scripts suites setup Standalone
+```
+
+Nun sollte der "Haupt-Enpunkt" unter `https://home.example.com:8080` und die API unter `https://authelia.example.com:9091` erreichbar sein. Achtung: es wird ein selbstsigniertes Zertifikat verwendet!
+Mithilfe der Hot-Reload kann jetzt gecoded werden.
+
+---
+
+Nach der Entwicklung kann die Testumgebung durch den folgenden Befehl wieder zurückgesetzt werden. 
+
+```
+go run ./cmd/authelia-scripts/ suites teardown Standalone
+```
+
+## Benutzerdefinierte Zertifikate
+
+Um ein benutzerdefiniertes Zertifikat für die Ausführung zu verwenden, muss die Datai `public.backend.crt` und `private.bakend.pem` unter [diesem](/internal/suites/common/pki/) Verzeichnis abgeändert werden. 
+Um die Gültigkeit zu testen, kann der folgendende Befehl ausgeführt werden.
+
+```
+curl https://auth.rpjosh.de:9091 --connect-to 'auth.rpjosh.de:9091:authelia.example.com:9091'
+```
+
+## Externe erreichbarkeit
+
+Im aktuellen Zustand sind die Endpunkte nur unter den Docker internen IP-Adressen erreichbar. Daher muss noch ein NAT Regel angelegt werden.
+
+```
+ip=$(ping -c 1 authelia.example.com | gawk -F'[()]' '/PING/{print $2}')
+sudo iptables -t nat -A PREROUTING -p tcp --dport 9091 -d 192.168.0.15 -j DNAT --to-destination 192.168.240.50:9091 -m comment --comment "Authelia-Test"
+sudo iptables -t nat -A PREROUTING -p tcp --dport 9092 -d 192.168.0.15 -j DNAT --to-destination 192.168.240.50:9092 -m comment --comment "Authelia-Test"
+sudo iptables -t nat -I OUTPUT -p tcp -o lo --dport 9091 -j DNAT --to-destination 192.168.240.50:9091
+```
+
+# Customizations
+
+Für das Starten des *gRPC* Servers müssen die folgenden Abhängigkeiten installiert werden.
+
+```
+go get github.com/envoyproxy/go-control-plane
+go get github.com/envoyproxy/go-control-plane/envoy/config/core/v3
+go get github.com/gogo/googleapis/google/rpc
+go get google.golang.org/grpc
+```
+
+## Konfiguration ändern
+
+Wenn die Konfiguration geändert wurde, müssen die Keys zur Validierung wieder erneut gebaut werden.
+
+```
+go run ./cmd/authelia-gen code keys
+```
+
+## Mocks abgeändert
+
+Wenn interfaces von den Mocks geändert werden, muss folgendes wieder ausgeführt werden:
+
+```
+export PATH=$PATH:$(go env GOPATH)/bin
+go generate ./...
+```
+
+## Bauen
+
+Um ein Docker Image für authelia zu bauen, müssen die folgenden Befehle ausgeführt werden.
+
+```sh
+# Dieser Befehle funktionieren aktuell nicht 
+authelia-scripts docker build
+authelia-scripts build
+
+# => Manuell bauen
+export CC=musl-gcc
+
+authelia-scripts build
+cp -r dist/public_html internal/server/
+go build -buildmode=pie -ldflags "-linkmode=external -s -w" -trimpath -buildmode=pie -o authelia ./cmd/authelia
+mv authelia authelia-linux-amd64-musl
+# Build docker image
+docker build --tag git.rpjosh.de/rpjosh/authelia/authelia:4.38.0-dev .
+docker push git.rpjosh.de/rpjosh/authelia/authelia:4.38.0-dev
+# Cleanup
+rm -rf internal/server/public_html/ ./authelia-linux-amd64-musl
+```
+
+# gRCP
+
+Um einen gRCP Endpunkt nutzen zu können, brauch mein eine *.proto* Datei. Für Envoy sieht diese wie in [dieser Datei](/ext-auth.proto) folgendermaßen aus.

+### Group Search Modes
+
+There are currently two group search modes that exist.
+
+#### Search Mode: filter
+
+The `filter` search mode is the default search mode. Generally this is recommended.
+
+#### Search Mode: memberof
+
+The `memberof` search mode is a special search mode. Generally this is discouraged and is currently experimental.
+
+Some systems provide a `memberOf` attribute which may include additional groups that the user is a member of. This
+search mode allows using this attribute as a method to determine their groups. How it works is the search is performed
+against the base with the subtree scope and the groups filter must include one of the `{memberof:*}` replacements, and
+the distinguished names of the results from the search are compared (case-insensitive) against the users `memberOf`
+attribute to determine if they are members.
+
+This means:
+
+1. The groups still must be in the search base that you have configured.
+2. The `memberOf` attribute *__MUST__* include the distinguished name of the group.
+3. If the `{memberof:dn}` replacement is used:
+   1. The distinguished name *__MUST__* be searchable by your directory server.
+3. The first relative distinguished name of the distinguished name *__MUST__* be search

+
+Requirements:
+
+1. Must be using the `memberof` search mode.
+2. Directory server must support searching by the first relative distinguished name as an attribute.
+
+Splits every `memberOf` value to obtain th e first relative distinguished name and joins all of those after surrounding
+them in parenthesis. This makes the general suggested filter pattern for this particular replacement
+`(|{memberof:rdn})`. The format of this value is as follows:
+
+```text
+(<RDN>)
+```
+
+For example if the user has the following distinguished names in their object:
+
+- CN=abc,OU=groups,DC=example,DC=com
+- CN=xyz,OU=groups,DC=example,DC=com
+
+The value will be replaced with `(CN=abc)(CN=xyz)` which using the suggested pattern for the filter becomes
+`(|(CN=abc)(CN=xyz))` which will then return any user that as a `CN` of `abc` or `xyz`.
