I need help/advise on ppolicy against Linux servers. I am running OpenLDAP 2.3.43-3.el5 (Red Hat rpm) on RHEL5.  I am using the ppolicy overlay.  The overlay seems to work to all of the tools, etc., that use this LDAP, except for the Linux servers.  With these servers, we get no expiry warning, and users can log in after the password has expired (unlimited).  We are using PAM/LDAP on these servers. Debugging this issue has caused me a bit of confusion.  In the LDAP logs, when logging into other equipment that 'binds as user', I see warnings, etc. returned:    ppolicy_bind: Setting warning for password expiry for uid=test_user,ou=people,o=theorg,dc=example,dc=net = 1251 secds BUT, since the Linux LDAP client has a separate 'binddn', I don't see these warnings when the Linux LDAP client does the ldapsearch to validate the user.  How does the policy work in this situation? Am I missing something here? Here's what I see when I log in as a users (second login, pwdGraceAuthNLimit=2): login as: test_user test_user@linux_box's password: Last login: Fri Oct 23 19:39:03 2009 from 10.50.1.135 [test_user@linux_box ~]$ [test_user@linux_box ~]$ ldapwhoami -x -D "uid=test_user,ou=people,o=theorg,dc=example,dc=net" -W -e ppolicy Enter LDAP Password: ldap_bind: Success (0) (Password expired, 1 grace logins remain) dn:uid=test_user,ou=people,o=theorg,dc=example,dc=net Result: Success (0) [test_user@linux_box ~]$ [test_user@linux_box ~]$exit Then on the next login: login as: test_user test_user@linux_box's password: Last login: Fri Oct 23 19:39:26 2009 from 10.50.1.135 [test_user@linux_box ~]$ [test_user@linux_box ~]$ ldapwhoami -x -D "uid=test_user,ou=people,o=theorg,dc=example,dc=net" -W -e ppolicy Enter LDAP Password: ldap_bind: Invalid credentials (49);
