Resetting rpd Password (Informative)

Question

Hello Everybody,
When i am doing some R&D work today, I come across a situation how to reset the password for rpd where I forgot the password for Administrator. All existed solutions (like NQSChangepassword.exe command) have associated with mentioning old password to get the new one.
The work around I found:
<li>Open NQSConfig.INI file </li>
<li>Go to Security part and find AUTHENTICATION_TYPE = BYPASS_NQS; </li>
<li>Uncomment this part </li>
<li>Stop the BI Server service </li>
<li>Close Administration Tool, if opened. (Then only the changes are affecting to the Administration Tool) </li>
<li>Open Administration Tool, then rpd which needs password reset, in offline mode </li>
<li>Give any password here, it accepts.</li>
<li>Now go to Manage > Security. </li>
<li>From here it’s the normal process how you change password for Administrator. </li>
<li>Save the changes to rpd </li>
<li>Revert back the changes in NQSConfig.INI </li>
<li>Start BI Server and open rpd with new password.</li>
I am not aware of whether it is bug or something else, and don’t even know any other best solution exists for the same. Using Import from Repository hope we can do this... As it's deprecated and the above procedure is the simple one, i am using this...
But this is the work around I found and want to let you all know this.
I blog it soon... :-)
Hope it's helpful...
Corrections & Comments are welcome... :)

Good find! :)
I've validated the procedure here, with a couple of observations:
1) If you delete or rename NQSConfig.ini the Admin Tool still loads (but requires the correct Administrator password)
2) If you invalidate the NQSConfig.ini (eg omit a closing square bracket from a section heading) then you get NQSError 47012 Syntax error in NQSConfig.ini file.
so it looks like the Admin tool will read the file if it's there (and honour the AUTHENTICATION_TYPE setting), but doesn't require it.
It would be interesting to raise this as an SR to find out if it's intended behaviour.
