Installation of a personalized authentication valve for DigDash

**Contents**

= Prerequisites =

* Have recovered the **CustomAuthenticator** folder in the **add-ons directory ** of the DigDash installation archive. It contains all the files necessary for setting up the personalized authentication valve in the DigDash Tomcat server. The placement of these files is described in this document.

12

** The Tomcat7 folder: the versions of the libraries for a Tomcat 7 server

13

** The Tomcat8 folder: the library versions for a Tomcat 8 server

14

* The following operations are to be performed **on the stopped DigDash server** .

15

16

= Configuration of the DigDash server =

17

18

== Copy of libraries ==

19

20

Add the libraries and the log configuration file from the **CustomAuthenticator / Tomcat <N>** folder (N: Tomcat version) to the folder

21

22

**<digdash_installation> / apache / lib** :

23

24

|custom_authenticator.jar|httpcore-4.4.9.jar

25

|commons-codec-1.10.jar|httpmime-4.5.5.jar

26

|commons-logging-1.2.jar|log4j-1.2.15.jar

27

|httpclient-4.5.5.jar|

__Libraries in the CustomAuthenticator / Tomcat8 folder__

30

31

== Addition of the personalized authentication valve ==

32

33

Add the custom authentication valve in the **context.xml** file located in the folder

34

35

**<digdash_installation> / apache-tomcat / conf**

36

37

To do this, add the following Valve element in the **Context** element .

...

<Valve className = "custom.apache.CustomAuthenticator"

43

sharedPasswd = "secret"

44

allowAddr = ". * Localhost. *,. * 127.0.0. *"

45

PortalUrl = "<url>? Login = $ { login} & amp; token = $ {token} "

46

fallbackAuth = " LDAP "

47

expectedResponse = " OK " />

</Context ...>

|Attribute|Description

56

|className|Name of the Java class, implementing the org.apache.catalina.Valve interface, to use as Valve here. This attribute is mandatory because it allows you to select the Valve to use. There are indeed several implementations provided by Tomcat.

57

|sharedPasswd|The shared password and verified at authentication (see point II.5)

58

|allowAddr|Regular expression (s) that the address for sending requests to the dashboard must satisfy. In the case of multiple regexes, separate with commas.

59

|portalUrl|(((

60

The address of the user verification page and the token.

61

62

- It can be unique and request validation from a single server; in that case:

63

64

<protocol>: ~/~/ <host>: <port> / <context> / <path> ? login = $ {login} & amp; token = $ {token}

65

66

- It can correspond to the address of the source issuing the access request to the dashboard; indicate in this case only the remaining path:

67

68

<context> / <path> ? login = $ {login} & amp; token = $ {token}

69

70

The valve will analyze in the header parameters of the incoming request the Referer to which to send the verification request.

71

)))

72

|fallbackAuth|Authentication method to use if the valve authentication fails.

73

|expectedResponse|Response returned by the page in the event of valid authentication (not case-sensitive), all other responses lead to authentication failure.

74

|print_debug|Optional, is false by default, otherwise add print_debug = " true " for more verbose traces.

115

116

It may be necessary, and **it is advisable** to specify on which server / domain the Dashboard will rely.

117

118

To do this, modify in the **web.xml** file in

119

120

**<digdash_installation> / apache-tomcat / webapps / digdash_dashboard / WEB-INF.**

122

To force the domain, change the value of the **FORCEDOMAIN** parameter to //true// .

123

Mention the domain name by changing the **DOMAIN** parameter .

124

125

To force the server address, change the value of the **FORCESERVERURL** parameter to //true// .

126

Mention the server address by changing the **SERVERURL** parameter .

* The example value for the SERVERURL parameter will almost always refer to localhost, when the dashboard and the server are placed in the same Tomcat server, which represents almost 99% of the uses. It will naturally be necessary to refer to the address of the external server if these two elements are placed on different servers.
