[Samba] Using ldap to check last password modification date

[술욱]

Hello,

For a portal I'm working on, I need to know if changing the unicodePwd
attr with LDAP also updates pwdLastSet (so the account doesn't get
locked). It seems the answer is yes, but the value I get from
pwdLastSet is somewhat weird:

pwdLastSet: 130753269490000000

That is Wed, 08 Jun 2011 11:31:34 GMT

Why? Is that epoch or something else? Is there anything else I need to
update when I change the user password using ldap?

Thanks!

Regards,
Norberto
