So for conn=1234 this would not fail. However, this particular conn=24903 has exactly before this err=53 the following in LDAP log:</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">conn=24903 op=20 BIND dn="uid=user1,dc=example,dc=org" method=128<br> conn=24903 op=20 RESULT tag=97 err=49 text=</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">This seems to suggest that any connection from the LDAP pool where some user failed to authenticate beforehand will not be usable afterwards. And worse, the connection validatation seems to re-use the respective latest credentials, instead of the service credentials that are configured in ldap.properties.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0"> </p> </td>
