During my R&D work today, i come across a situation how to reset the password for rpd where I forgot the old password. All existed solutions (like NQSChangepassword.exe command) have associated with mentioning old password to get the new one.
The work around I found:
Open NQSConfig.INI file
Go to Security part and find AUTHENTICATION_TYPE = BYPASS_NQS;
Uncomment (remove #) this part.
Stop the BI Server service
Close Administration Tool, if opened. (Then only the changes are affecting to the Administration Tool)
Open Administration Tool, then rpd which needs password reset, in offline mode
Give any password, it accepts.
Now go to Manage > Security.
From here it’s the normal process how you change password.
Save the changes to rpd
Revert back the changes in NQSConfig.INI
Start BI Server and open rpd with new password.
I am not aware of whether it is this bug or something else. And there is also a way to do this using Import from Repository. But this is deprecated option. Of course, i found that my approach is an easy way and not time consuming process
