Hi!
Me again after 10 years with basically the same question (https://www.openldap.org/lists/openldap-technical/201411/msg00044.html): What is the meaning of messages like these (note the number of messages created):
Nov 19 11:53:47 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040879 seconds Nov 19 11:53:50 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040876 seconds Nov 19 11:53:52 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040874 seconds Nov 19 11:53:54 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040872 seconds Nov 19 11:53:57 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040869 seconds Nov 19 11:53:59 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040867 seconds Nov 19 11:57:41 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040645 seconds Nov 19 11:57:44 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040642 seconds Nov 19 11:58:01 v07 slapd[2606]: ppolicy_bind: Setting warning for password expiry for uid=user = 1040625 seconds ...

So the server logs such an entry every few seconds. I might guess that the user tried to authenticate every few seconds (for whatever reason). But what I wonder most: The LDAP server does not seed to "set" the password expiration; it just has to check the value. And for the latter I see no need to log it in syslog. It seems the number is the number of seconds until the password actually expired.
So is that a (historic) bug?
And yes, I'm still running a historic 2.4 version of OpenLDAP, so no need to tell me that it's quite old. (Despite of that we really intend to upgrade, but the more persons involved, the loger it takes...)
Kind regards, Ulrich
