With samba 4.2 and samba configured as a PDC with a windows 8.1 client
it still errors out with 0x80090345 when raising the credential manager,
the fix for this https://bugzilla.samba.org/show_bug.cgi?id=11097 tweaks
the BackupKey Remote Protocol (MS-BKRP) but afaics with Samba in PDC
mode the windows client doesn't even try to use this protocol (which
MS-BKRP says is for AD anyway)
I've pored over the associated logs and network traces for this but find
no errors or details in the conversation with the samba PDC to explain
why this error is triggered. Additionally it seems that users that
previously were logged in (prior to install of KB2992611)  to the win8.1
client don't raise the error, however if a user not previously logged is
used bingo attempt to raise the Cred Manager and you get  0x80090345.
Does anyone have any more info on this,  is it really the case that for
samba in PDC mode that there is nothing more that can be done  :/
