I don't see the key being populated, but when I call MDB_GET_CURRENT after the use of MDB_GET_MULTIPLE the key is the value I expect. Looking through the code I don't see the key getting used in this path.

[Issue 9302] New: ppolicy pwdFailureTime race condition leaves acccount unlocked, violating pwdLockout policy
by openldap-its＠openldap.org 03 Sep '20

https://bugs.openldap.org/show_bug.cgi?id=9302 Issue ID: 9302 Summary: ppolicy pwdFailureTime race condition leaves acccount unlocked, violating pwdLockout policy Product: OpenLDAP Version: 2.4.50 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: requate(a)univention.de Target Milestone: --- Multiple concurrent ldap binds with invalid passwords against a user account sometimes don't trigger account lockout, even though the number of failed attempts exceeds the configured pwdLockout policy of the ppolicy overlay. How to reproduce: 1. Configure ppolicy overlay with pwdLockout: TRUE 2. set pwdMaxFailure to some value, e.g. 5 3. Create a test user account and start just enough (or more) parallel ldapsearch processes to make the account get locked, e.g. like this in bash/sh (note the backgrounding): for i in $(seq 6); do ldapsearch -x -D "uid=testuser1,$ldap_base" -w invalid >/dev/null 2>&1 & done 4. Check relevant ppolicy attributes, like: ldapsearch -x -H LDAPI:// -b "uid=testuser1,$ldap_base" + \ grep -E '^(pwdFailureTime|pwdAccountLockedTime):' This often shows no pwdAccountLockedTime but enough (or more) pwdFailureTime values to meet the lockout policy. -- You are receiving this mail because: You are on the CC list for the issue.

We tried to call "ldap_set_option( ld, LDAP_OPT_NETWORK_TIMEOUT, (void *) &nettimeout )" before ldap_start_tls_s and it works well! -- You are receiving this mail because: You are on the CC list for the issue.
