LDAP / YAST password encryption

Hi, I’ve installed LDAP on a clean 11.2 install using the instructions from Integrating LDAP and Samba using openSUSE. I’ve set the LDAP user password encryption to blowfish in YAST2.

I now have a problem when I add LDAP users through YAST2. The passwords are being stored in LDAP unencrypted. Strangely they are all prefixed by ‘{blowfish}’.

How do I get new users passwords encrypted properly? I’m sure it’s something obvious, I just can’t see it!
