yes. I was ssh-ing to another LDAP client.

No, that command appeared to be successful. It would return the output:
modifying entry "uid=jdoe,ou=People,dc=domain,dc=edu"
But after the command was executed, ssh would then fail with
"Permission denied" errors.

Yes. The user (or root) could change the password if "cn=Directory
Manager" was replaced with "uid=jdoe,ou=People,dc=domain,dc=edu" and
the user's
old password was supplied in the command.
Detailed summary:
On an LDAP client, the users root and jdoe could successfully change
jdoe's password by using the following command:
(1) ldappasswd -h
my389dsserver.domain.edu -p 389 -ZZ -D
"uid=jdoe,ou=People,dc=domain,dc=edu" -w -s current_jdoe_passwd -s
new_jdoe_passwd "uid=jdoe,ou=People,dc=domain,dc=edu"
However, on the same LDAP client, using the command:
(2) ldappasswd -h
my389dsserver.domain.edu -p 389 -ZZ -D
"cn=Directory Manager" -w directorymanager_password -s
new_user_password "uid=jdoe,ou=People,dc=domain,dc=edu"
would "appear" to change the password, but would simply render the
password unusable. Both the old and new passwords would fail with
"Permission Denied" errors when ssh was used to
login to another LDAP client.
This process was attempted with the subtree password policy applied at
the domain level, but with the "Password Syntax" disabled.
Deleting the subtree password policy, and re-adding the same policy to
the domain corrected the issue.
Give me a little time to dig out the data in the access logs. I'll
sanitize the output and send it along.
Could you try the following command lines
and share the test steps as
well as the access log associated with the operations?
When setting a new_jdoe_passwd/new_user_password, please avoid shell
sensitive character such as '!' for this testing.
$ ldappasswd -h
-p 389 -ZZ -D
"uid=jdoe,ou=People,dc=domain,dc=edu" -w current_jdoe_passwd -s
new_jdoe_passwd "uid=jdoe,ou=People,dc=domain,dc=edu"
$ ldapsearch -h
-p 389 -D
"uid=jdoe,ou=People,dc=domain,dc=edu" -w new_jdoe_passwd -b "" -s
base
$ ldappasswd -h
-p 389 -ZZ -D "cn=Directory
Manager" -w directory manager_password -s new_user_password
"uid=jdoe,ou=People,dc=domain,dc=edu"
$ ldapsearch -h
-p 389 -D
"uid=jdoe,ou=People,dc=domain,dc=edu" -w new_user_password -b "" -s
base
Thanks.
