Hi list, Okay, I have mostly got the disabling errors of samba 3.5.4 on Openindiana sorted. Things like child smbd processes core dumping/dying (max groups set to 16 only by default in opensolaris kernel) and being unable to create sid-uid/sid-gid mappings. What remains is finding out why winbind in samba 3.5.4 no longer automatically creates new mappings. Any pointers on where to look? Right now I do not have to create a lot of mappings but it is not going to fun later when I have to do hundreds manually at the start of the new school year. regards, Christopher
