Description Kirin van der Veer 2014-12-03 01:50:31 UTC
The windows DPAPI fails after repeated user password change on Windows 7.
According to this bug report for UCS:
It is caused by the RSA modulus not being set to 2048 bits.

Samba developer Andrew Bartlett commented on the samba mailing list here:
That a patch would require a reviewer and testing to ensure against regressions.

This bug has been created to track when mainline samba implements a fix.
