ScharfViktor: I would suggest to implement case where admin change userPassword - the most likely case in the real life of the product. And if you also check that the user is logged in with a new password, that would be great.
- user1 forgets his password
- admin changes password
- user1 logs in using new password

+# Docs Helpers
+
+`docs/helpers` contains a small go program creating docs by extracting information from the code. It is manually started with `make docs-generate` or via the CI and has three main responsibilities:
+
+- Generate docs for envvars in config structs
+- Extract envvars that are not mentioned in config structs (aka "Rogue" envvars)
+- Generate docs for rogue envvars
+
+Output:
+
+- The generated yaml files can be found at: `docs/services/_includes` when running locally respectively in the docs branch after the CI has finished.
+- The generated adoc files can be found at: `docs/services/_includes/adoc` when running locally respectively in the docs branch after the CI has finished.
+- The file name for rouge envvars is named: `global_configvars.adoc`.
+
+Admin doc process:
+
+Whenever a build from the admin documentation is triggered, the files generated here are included into the build process and added in a proper manner defined by the admin documentation.
+
+Genreal info:
+
+"Rouge" envvars are variables that need to be present *before* the core or services are starting up as they depend on the info provided like path for config files etc. Therefore they are _not_ bound to services like other envvars do. 
+
+It can happen that rouge envvars are found but do not need to be published as they are for internal use only. Those rouge envvars can be defined to be ignored for further processing.
+
+IMPORTANT:
+
+- Once a rouge envvar has been identified, it is added to the `global_vars.yaml` file but never changed or touched by the process. There is one exception with respect to single/double quote usage. While you manually can (and will) define a text like: `"'/var/lib/ocis'"`, quotes are transformed by the process in the .yaml file to: `'''/var/lib/ocis'''`. There is no need to change this back, as the final step transforms this correctly to the adoc table.
+
+- Because rouge envvars do not have the same structural setup as "normal" envvars like type, description or defaults, these infos need to be provided manually one time - even if found multiple times. Any change on this info will be used on the next CI run and published on the next admin docs build.
+
+- Do not change the sort order of rouge envvar blocks as they are automatically reordered alphabetically.
+
+## Generate Envvar docs for config structs
+
+Generates docs from a template file, mainly extracting `"env"` and `"desc"` tags from the config structs.
+
+Templates can be found in `docs/helpers` folder. (Same as this `README`.) Check `.tmpl` files
+
+## Extract Rogue Envvars
+
+It `grep`s over the code, looking for `os.Getenv` and parses these contents to a yaml file along with the following information:
+```golang
+// Variable contains all information about one rogue envvar
+type Variable struct {
+	// These field structs are automatically filled:
+	// RawName can be the name of the envvar or the name of its var
+	RawName string `yaml:"rawname"`
+	// Path to the envvar with linenumber
+	Path string `yaml:"path"`
+	// FoundInCode indicates if the variable is still found in the codebase.
+	FoundInCode bool `yaml:"foundincode"`
+	// Name is equal to RawName but will not be overwritten in consecutive runs
+	Name string `yaml:"name"`
+
+	// These field structs need manual filling:
+	// Type of the envvar
+	Type string `yaml:"type"`
+	// DefaultValue of the envvar
+	DefaultValue string `yaml:"default_value"`
+	// Description of what this envvar does
+	Description string `yaml:"description"`
+	// Do not export this envvar into the generated adoc table
+	Ignore bool `yaml:"do_ignore"`
+
+	// For simplicity ignored for now:
+	// DependendServices []Service `yaml:"dependend_services"`
+}
+```
+This yaml file can later be manually edited to add descriptions, default values, etc.
+
+IMPORTANT: `RawName`, `Path` and `FoundInCode` are automatically filled by the program. DO NOT EDIT THESE VALUES MANUALLY.
+
+## Generate Rogue Envvar docs
+
+It picks up the `yaml` file generated in `Extract Rogue Envvars` step and renders it to a adoc file (table) using a go template.
+
+The adoc template file for this step can be found at `docs/templates/ADOC_global.tmpl`.

+Feature: edit user
+
+  Note - this feature is run in CI with ACCOUNTS_HASH_DIFFICULTY set to the default for production
+  See https://github.com/owncloud/ocis/issues/1542 and https://github.com/owncloud/ocis/pull/839
+
+  Background:
+    Given user "Alice" has been created with default attributes and without skeleton files
+    And the administrator has given "Alice" the role "Admin" using the settings api
+    And the user "Alice" has created a new user using the Graph API with the following settings:
+      | userName    | Brian             |
+      | displayName | Brian Murphy      |
+      | email       | brian@example.com |
+      | password    | 1234              |
+
+
+  Scenario: the admin user can edit another user email
+    When the user "Alice" changes the email of user "Brian" to "newemail@example.com" using the Graph API
+    Then the HTTP status code should be "200"
+    And the user "Brian" should have information with these key and value pairs:
+      | key  | value                |
+      | mail | newemail@example.com |
+
+
+  Scenario: the admin user can override an existing user email of another user
+    When the user "Alice" changes the email of user "Brian" to "brian@example.com" using the Graph API
+    Then the HTTP status code should be "200"
+    And the user "Brian" should have information with these key and value pairs:
+      | key  | value             |
+      | mail | brian@example.com |
+
+
+  Scenario: the admin user cannot clear an existing user email
+    When the user "Alice" tries to change the email of user "Brian" to "" using the Graph API
+    Then the HTTP status code should be "400"
+    And the user "Brian" should have information with these key and value pairs:
+      | key  | value             |
+      | mail | brian@example.com |
+
+
+  Scenario Outline: a normal user should not be able to change their email address
+    Given the administrator has given "Brian" the role "<role>" using the settings api
+    When the user "Brian" tries to change the email of user "Brian" to "newemail@example.com" using the Graph API
+    Then the HTTP status code should be "401"
+    And the user "Brian" should have information with these key and value pairs:
+      | key  | value             |
+      | mail | brian@example.com |

+      | displayName | Carol King        |
+      | email       | carol@example.com |
+      | password    | 1234              |
+    When the user "Brian" tries to change the email of user "Carol" to "newemail@example.com" using the Graph API
+    Then the HTTP status code should be "401"

+    Given user "Brian" has uploaded file with content "test file for reset password" to "/resetpassword.txt"
+    When the user "Alice" resets the password of user "Brian" to "newpassword" using the Graph API
+    Then the HTTP status code should be "200"
