CUPS+samba

Dear all. I have a box, running SuSE 8.1 and serving as a print server for windows clients, of cource, running CUPS and SAMBA. Of cource, I have "printing=cups" enabled in smb.conf, and the common [printers] section. , and all windows clients use my CUPS printers well. But i have one problem: I cannot access the CUPS classes unless i specify them explicitly as printing shares in smb.conf. does anybody else suffer from this? Sincerelly, Vitaly
