I haven't seen this come up but...

We use LDAP authentication for GroupWise against eDir. We have
password expiry set up.

The situation that a couple of us have experienced is:
1). Password Expires
2). ActiveSync Client eats up all of the grace logins
3). Add additional grace logins, change password
4). If you don't change the password on the ActiveSync account,
reasonably promptly, then it will lock your account, when you go to add
the correct password in it won't sync because your account is locked -
so the password doesn't get changed. Unlock your account, try again,
if you don't do it promptly your account will get locked again.

It would be good if the GroupWise Connector could stop subsequent login
attempts when a password has expired and resume once the password has
been updated...
