[Fedora-directory-commits] console/src/com/netscape/management/client/util ADUtil.java, NONE, 1.1

[Richard Allen Megginson]

Author: rmeggins

Update of /cvs/dirsec/console/src/com/netscape/management/client/util
In directory cvs1.fedora.phx.redhat.com:/tmp/cvs-serv1890/console/src/com/netscape/management/client/util

Added Files:
	ADUtil.java 
Log Message:
Resolves: bug 158334
Bug Description: WinSync Console: Handling of logonHours and
accountExpires incorrect.
Reviewed by: nhosoi (Thanks!)
Files: new file ADUtil.java
Fix Description: Added code to convert from Windows FILETIME to Java
time.  Added special handling for the "Never Expires" value, which can
be the very large value or 0.  The console now displays "Never Expires"
or the actual human readable value for the time.
As far as Logon Hours, it's just really messed up.  I will open another
bug for that.
https://bugzilla.redhat.com/attachment.cgi?id=326573 - never expires
https://bugzilla.redhat.com/attachment.cgi?id=326574 - expires with date
Platforms tested: RHEL5
Flag Day: no
Doc impact: yes
