Attachment opens login page

[srivatsatatti]

Whenever an agent tries to open an attachment file, a new window with login (index.pl) screen gets open.

Any idea on this

Using OTRS-3.0.11
RHEL

[srivatsatatti]

and same for stats when report is of print format.

Guess its a serious problem, Can any one help pls...

At customer portal even when customer tries to read the articlet the .pl file is executing (customer.pl).

If i check the URL its showing as http://[servername]/otrs/index.pl/filename.txt?Action=Attachment;ArticleID=520;Fileid=2
and so its executing index.pl/customer.pl displaying login screen again.Is this correct?

Any help would be much appreciated.
