HTTP DELETE method for unauthenticated user

  • 1.  HTTP DELETE method for unauthenticated user

    Posted Sun October 01, 2023 02:40 AM

    Dear All,

    I would like to request some hints / help on above mentioned topic. In our side there is a standard junction (ISVA 10.0.6.0 , on-prem) where we would like to accept / enable "HTTP DELETE" method for a particular path (behind on junction).

    I don't have any issue if I use normal authenticated user session together with ACL settings "Any-other Tmdrx".  I have got result back "<P>DELETE operation successful</P>"

    But, if I set these ACLs and call URL without authentication:

    Any-other Tmdrx

    Unauthenticated Tmdrx

    I always get back a login request from Webseal in order to get user authentication. 

    Question:  is "HTTP DELETE" method possible only for authenticated users?

    Additional note: this setting doesn't contain "PUT, DELETE"  in Webseal configuration:  http-method-disabled-remote = TRACE,CONNECT

    Regards,

    Janos,

     

    The 'd' ACL bit should be checked on a DELETE operation, and so setting 'unauthenticated' on the ACL to 'Tmdrx' should work. 

     

    The best thing to do is to enable 'pdweb.wan.azn' tracing and then request the resource as the unauthenticated user.  You should see trace information pertaining to the authorization decision, including the object name which is being used, the ACL which is being checked, and the ACL bits which are being used in the authorization decision.  Hopefully this will help you to work out what is happening in your environment.

     

    I hope that this helps.

    Hello Scott,

    Thanks, we have check AZN logs and found that a POP was a root cause here.  Remove POP it is working as we expected.
