Re: Password Sync - Extended Characters nothing happnes?

Hi,

  The password sync service between AD and Directory server appears to “can” passwords with extended characters.
  I’m working for a client in Belgium at the moment and they’re quite accent happy with passwords.

  Now, Active Directory happily accepts these passwords but I don’t even get a sniff of the password change attempt in the audit log from in 389-DS.
  Is this a bug or by design ?

Thanks Rich ( I don’t normally get access to windows logs J).

04/02/12 14:42:22: Modify password failed for remote entry: uid=<user>,ou=People,<blah>
04/02/12 14:42:22: Deferring password change for <user>
04/02/12 14:42:24: Ldap error in ModifyPassword
      19: Constraint violation

No problem, bit of digging around tells me that there is a 7 bit character constraint on passwords (7-bit check plugin).
What I don’t understand is why there is nothing on the Linux side, surely:
04/02/12 14:42:24: Ldap error in ModifyPassword
Means that the password change has been attempted and rejected by the server, so why am I not seeing anything in the logs on the server?
Do you see any connections at all from the AD box in your directory server access log?  /var/log/dirsrv/slapd-INSTANCE/access

Yes, I’ve got this with a tome stamp matching when the user changed their AD password 14:42:21, and 2 seconds later 14:42:23 (there is more of the same every few seconds until it gives up):

Having seen the error logged on the AD Server I guess I should be looking for these entries (err=19) then?:
[02/Apr/2012:14:42:21 +0200] conn=14516 op=2 RESULT err=19 tag=103 nentries=0 etime=0

Anyway to get these password failures logged to audit?

Brett
