From: friedrich dot grosse at gmail dot com Operating system: Windows Server 2008 R2 PHP version: 5.4.8 Package: COM related Bug Type: Bug Bug description:DCOM does not work with Username, Password parameter
Description: ------------ I try to instantiate a DCOM object on a remote machine (Windows Server 2008 R2) in another domain using the Username and Password parameters of the COM class constructor [1] I did also figure out that there is a Domain parameter which is not mentioned in the manual at [1]. However I can not authenticate at the remote machine. The event log there indicates that only the first character of the Logon Accounts Username has been transmitted to the DCOM Server. The Domain parameter has been received completely. I am not familiar with PHP internals but I did a quick look in the source code and would guess that the issue can be traced back to [2]. The user_name and user_name_len are already parsed some lines above. Why is php_com_string_to_olestring called with a -1 as second parameter which leads to determining the length of the username again? Maybe giving user_name_len instead of -1 could fix this issue?
