Hi,
I am trying to configure webdav to provide web resource to multiple user.
For example, inside webdav directory I create multiple user directory (
user1, user2 ,user3 ....). I am authenticating users using mysql database (
authentication works fine for single user ( let us say user1) with role name
user1). But it doesn't work for multiple users. Here is snippet of
web.xmlfile in webapps/webdav/WEB-INF/
web.xml ( specifically security constraint I am trying to set). Please note
that as specified in following XML parameters, admin and user1 are able to
authenticate with database. All users/roles are correctly specificed. what i
want is to provide admin access to admin for "/webapps/webdav/" directory
and user1 access of "/webapps/webdav/user1" directory. I have created user1
directory inside webapps.
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/user1/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>user1</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Tomcat Manager Application</realm-name>
</login-config>
<security-role>
<description>
The role that is required to log in to the Manager Application
</description>
<role-name>admin</role-name>
<role-name>user1</role-name>
</security-role>if i try webdav access through
http://xxx.xxx.xxx.xxx:8080/webdav/user1 and enter username and password, it
gives following error on web page:

Please help. Can we configure webdav application to provide exclusive
access of a subdirectory to multiple user ?
