Has anyone connected Guvnor on Apache Tomcat to Active Directory? I know the
components.xml file is where we setup the security, but I haven't been able to find
any examples of using active directory in my config. I am using 5.1.1 of Guvnor, 7.x of
Tomcat, on a windows server.
Any thoughts?
Thanks

This is the configuration I have used in components.xml in Guvnor 5.1.1 on Tomcat 6.x,
linux server:
<!-- SECURITY IDENTITY CONFIGURATION -->
<security:ldap-identity-store name="ldapIdentityStore"
server-address="xxx.xxx.xxx"
server-port="389"
bind-DN="CN=*******,OU=xxx,OU=xxx,DC=xxx,DC=xxx,DC=xxx"
bind-credentials="*******"
user-DN-prefix="CN="
user-name-attribute="sAMAccountName"
user-DN-suffix=",OU=xxx,OU=xxx,OU=xxx,DC=xxx,DC=xxx,DC=xxx"
user-context-DN="OU=xxx,DC=xxx,DC=xxx,DC=xxx"
role-DN-prefix="CN="
role-name-attribute="member"
role-object-classes="group"
role-DN-suffix=",OU=xxx,DC=xxx,DC=xxx,DC=xxx"
role-context-DN="OU=xxx,DC=xxx,DC=xxx,DC=xxx"
user-role-attribute="memberOf"
user-object-classes="user"
role-attribute-is-DN="false" />
<security:identity-manager identity-store="#{ldapIdentityStore}" />
<!-- <security:identity
authenticate-method="#{authenticator.authenticate}"/> -->
Note: The authenticate-method is commented out. This allows for a custom authentication
method and is not required in this instance.
I also found that if a user authenticates with a blank or empty password, they are
authenticated and given the role of anonymous. As Drools Guvnor only uses external
authentication and manages authorisation internally, this allowed users to log in with a
blank or empty password, essentially circumventing authentication.
This was addressed by modifying the SecurityServiceImpl with Guvnor to prevent this:
// Modified from original to ensure no empty or blank passwords
if ( password == null || password.trim().equals("")) {
return false;
}
A further modification removed log.errors to improve the readability of log files.
// Changed log.error to log.warn with userName
log.warn( "Unable to login user [" + userName + "]" );
Autologin was also disabled. This is a feature of Guvnor to support out of the box use
without security. However it caused multiple spurious logging errors.
// Disable autologin
return new UserSecurityContext( null );
//check to see if we can autologin
//return new UserSecurityContext( checkAutoLogin() );

Ross,
Thank you for the detailed recommendation. We've been working to get this
straightened out and finally have our authentication worked out except for the null
password issue. Do you have a compiled version of that jar for 5.1.1? We've been
trying to compile this through the guvnor project, but keep having issues with
dependencies. Any suggestions?

Ross,
As Dean indicated, we have our Guvnor/ActiveDirectory implementation working and we know
how to remediate the null password issue, but cannot get a 5.1.1 version to compile. If
you can return us a .jar or .class file for the source noted below that would be great.
If you can also give us any guidance on how to get a build configuration working properly
that is also appreciated as we would like to be able to make modifications (if the need
arises).
Thanks in advance,
- Ron Rock.

Hi Ron/Dean,
The approach I used was not to build guvnor from source but use a maven war
overload, that way you can separately manage any changes from the original
source.
There is one tricky bit I found though. You must use the guvnor war from the
download distribution, not the one that's in the jboss mvn repo. For some
reason they are different, and you will see GWT warnings about serialization
if you get the wrong one.

Ross,
As Dean indicated, we have our Guvnor/ActiveDirectory implementation
working and we know how to remediate the null password issue, but cannot get
a 5.1.1 version to compile. If you can return us a .jar or .class file for
the source noted below that would be great. If you can also give us any
guidance on how to get a build configuration working properly that is also
appreciated as we would like to be able to make modifications (if the need
arises).
Thanks in advance,

Ross,
Thank you for the detailed recommendation. We've been working to get this
straightened out and finally have our authentication worked out except for
the null password issue. Do you have a compiled version of that jar for
5.1.1? We've been trying to compile this through the guvnor project, but
keep having issues with dependencies. Any suggestions?

Subject: Re: [rules-users] Guvnor, Apache Tomcat, and Active directory
This is the configuration I have used in components.xml in Guvnor 5.1.1 on
Tomcat 6.x, linux server:
<!-- SECURITY IDENTITY CONFIGURATION --> <security:ldap-identity-store
name="ldapIdentityStore"
server-address="xxx.xxx.xxx"
server-port="389"
bind-DN="CN=*******,OU=xxx,OU=xxx,DC=xxx,DC=xxx,DC=xxx"
bind-credentials="*******"
user-DN-prefix="CN="
user-name-attribute="sAMAccountName"
user-DN-suffix=",OU=xxx,OU=xxx,OU=xxx,DC=xxx,DC=xxx,DC=xxx"
user-context-DN="OU=xxx,DC=xxx,DC=xxx,DC=xxx"
role-DN-prefix="CN="
role-name-attribute="member"
role-object-classes="group"
role-DN-suffix=",OU=xxx,DC=xxx,DC=xxx,DC=xxx"
role-context-DN="OU=xxx,DC=xxx,DC=xxx,DC=xxx"
user-role-attribute="memberOf"
user-object-classes="user"
role-attribute-is-DN="false" />
<security:identity-manager identity-store="#{ldapIdentityStore}" />
<!-- <security:identity
authenticate-method="#{authenticator.authenticate}"/> -->
Note: The authenticate-method is commented out. This allows for a custom
authentication method and is not required in this instance.
I also found that if a user authenticates with a blank or empty password,
they are authenticated and given the role of anonymous. As Drools Guvnor
only uses external authentication and manages authorisation internally, this
allowed users to log in with a blank or empty password, essentially
circumventing authentication.
This was addressed by modifying the SecurityServiceImpl with Guvnor to
prevent this:
// Modified from original to ensure no empty or blank passwords if (
password == null || password.trim().equals("")) {
return false;
}
A further modification removed log.errors to improve the readability of log
files.
// Changed log.error to log.warn with userName log.warn( "Unable to login
user [" + userName + "]" );
Autologin was also disabled. This is a feature of Guvnor to support out of
the box use without security. However it caused multiple spurious logging
errors.
// Disable autologin
return new UserSecurityContext( null );
//check to see if we can autologin
//return new UserSecurityContext( checkAutoLogin() );

Subject: [rules-users] Guvnor, Apache Tomcat, and Active directory
Has anyone connected Guvnor on Apache Tomcat to Active Directory? I know
the components.xml file is where we setup the security, but I haven't been
able to find any examples of using active directory in my config. I am
using 5.1.1 of Guvnor, 7.x of Tomcat, on a windows server.
Any thoughts?
Thanks
