I just resolved this issue. Bind account password expired. From: openldap-technical [mailto:openldap-technical-bounces@openldap.org] On Behalf Of Lang, Adam Sent: Tuesday, November 27, 2018 1:00 PM To: openldap-technical(a)openldap.org Subject: openldap stopped authenticating Hello, I woke up to an issue today where SSH access to our servers no longer works due to issues with LDAP authentication. Oddly, ldapsearch with admin credentials interacts with the LDAP server fine. If I check for ldapusers using getent passwd, none are returned. The slapd auditlog records the failed attempts. When trying to su as an ldap user, it returns "no passwd entry". Nothing "should" have changed over night, so any ideas of where to look will be appreciated.
