Resolves: bug 207893
Bug Description: Adding a pre-hashed password to DS when using Windows 
Password
  Syncronization will trigger a loop condition of password updates.  The 
DS will
  send the hashed password to AD, which thinks it's clear-text.  AD 
stores the
  password, attempts to bind to DS using the hash (which of course 
fails), so it
  sends the hashed password back to DS.  This goes round and round.

Branch: HEAD
Fix Description: This fix first checks if there is a password storage 
scheme at
  the beginning of the userpassword attribute value before syncing it.  
If there
  is a storage scheme present, a message is logged at the replication 
logging level
  that this hashed password is being skipped instead of just trying to 
sync it.

  If someone adds a password with the clear prefix on it to DS (such as
  "{clear}secret"), we will detect that and strip off the "{clear}" 
prefix before
  sending it to AD.  All other passwords that start with the "{" 
character and
  contain the "}" character somewhere else in the password will be 
considered to
  be already hashed.
Platforms tested: FC6 & Windows 2003 Server
