Hello,

We have a Sharepoint 2010 with SQL 2008 r2 reporting services integrated with sharepoint. We also have a forefront TMG firewall for external  users. Internally users are able to access sharepoint and launch the reportbuilder application download and launch without issue. External users are able to login and access site the problem comes when they click the "new/Reportbuilder report" from the Documents/New Document Drop down menu" . the forefront tmg box is in DMZ and is not a member of domain and is using LDAP to authenticate external sharepoint users. We really need to allow for external users to launch report builder without the use of VPN. 

Thanks.

Hi,

LDAP authenticate should be successful because external users can login and access site.

Please check TMG log to see whether there are some helpful information.

Best Regards,

Joyce

As mentioned external users are authenticating and using the rest of the site successfully it is only when launching report builder that this issue occurs. Going through logs nothing useful yet.
