On : Identity Synchronization For Windows, and the Directory Server's pswdsync plugin.
When attempting to validate password on ODSEE after change on AD, ISW's On demand synchronization is failing from the DSEE/ODSEE to AD at the pswdsync plugin. Attribute changes are being synchronized properly but user passwords are not.

ISW configuration is set up to where interaction with the Active Directory server is over SSL (port 636). It was discovered that a domain cert had expired and had failed to auto renew. On a Windows server, a reboot should have forced the server to renew its cert. The expiration of the cert corresponds with the time that "on demand authentication" began to fail. Because its a domain cert, it had an affect on both Global Catalog (GC) servers and any other AD servers in the ELS domain. Customer corrected the problem and the cert has been renewed.
