Hello, I believe I found a bug with samba. I'm running 2.2.8a on a Solaris 8 machine. I notice that if I have a parent directory with an ACL like: --- snip of acl from parent directory --- # file: testing/ # owner: loughlin # group: other user::rwx user:loughlin:rwx #effective:rwx user:dannytest:rwx #effective:rwx group::r-x #effective:r-x mask:rwx other:r-x default:user::rwx default:user:loughlin:rwx default:user:dannytest:rwx default:group::r-x default:mask:rwx default:other:r-x When I create a subfolder within the parent in Unix I get the correct results: # file: sub/ # owner: loughlin # group: other user::rwx user:loughlin:rwx #effective:rwx user:dannytest:rwx #effective:rwx group::r-x #effective:r-x mask:rwx other:r-x default:user::rwx default:user:loughlin:rwx default:user:dannytest:rwx default:group::r-x default:mask:rwx default:other:r-x However, when I map my share and create a subfolder in the parent I get the following ACLs: # file: sub2/ # owner: loughlin # group: staff user::rwx user:loughlin:rwx #effective:r-x user:dannytest:rwx #effective:r-x group::r-x #effective:r-x mask:r-x other:r-x default:user::rwx default:user:loughlin:rwx default:user:dannytest:rwx default:group::r-x default:mask:rwx default:other:r-x Notice that the mask gets changed... Here is a snip of my smb.conf for this share: [testing] path = /home/e121/loughlin/testing username = loughlin, dannytest valid users = loughlin, dannytest read list = loughlin, dannytest write list = loughlin, dannytest read only = No inherit permissions = Yes inherit acls = Yes The work around is to create an acl with a group id (ie group:other:rwx) and give it the value of the mask. Then add "force group = other" to the entry in smb.conf. Daniel Loughlin
