Just to jump into the conversation :) I'd also like to run Samba with an LDAP backend (Domino) on SLES 9. It sounds like this issue would also affect such an installation..? It works on SLES 8. Additionally, is it not possible to setup NIS to use LDAP and configure Samba to use local authentication? I'll be finding out soon enough, but it's best to ask before upgrading $50k production servers :) TIA, -Patrick
