[bug] Creation/LastLogon not always decoded or set to current time

[jmbesnard]

Hello,

I wanted to try your library to decode a large set of msDS-KeyCredentialLink attributes gathered from the LDAP of an Active Directory.

On computers, I am getting the following error: Warning: An error occurred processing a line. Error: 'NoneType' object has no attribute 'toFormatD'

On users, the LastLogonTime and CreationTime always show the current time. Is this to be expected ?

Thanks
