Unable to Add User

[mahesh_alfresco]

When I try to search and adding User on the site, it shows following error:

11150004 Wrapped Exception (with status template): 11150008 Failed to execute script 'classpath*:alfresco/templates/webscripts/org/alfresco/repository/site/membership/potentialmembers.get.js': 11150007 Access Denied. You do not have the appropriate permissions to perform this operation.

When i try "Start Workflow" > New Task > Assign To

It shows the following Error:

org.alfresco.repo.security.permissions.AccessDeniedException: 11150012 Access Denied. You do not have the appropriate permissions to perform this operation.

Ok.  What is the default configuration file name..? Where i can get it..?

Actually in the directory, i could see only "unsecured-custom-public-services-security-context.xml.sample"  which consists only templates tags...

Should i use the same file or something else.... ?

Default file can be found in the source code: https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/config/al... 

Ideally you would delete the custom-/unsecured-* files and revert back to the default configuration bundled in the default web application.
