Conﬁguring Samba ACL Support

on the ACL scheme list for that share. Otherwise, Samba will make

many system calls for other ACL schemes before it locates the right one.

This prioritization will become even more important in the future when

Samba supports more and more ACL types.

For HP CIFS Version A.01.08

With HP CIFS Server version A.01.08, the “nt acl support” conﬁguration

variable is made share level. It was previously a Global level variable. Its

default value is “yes”. Using this variable, users can now control the ACL

support on a per-share basis.

Except for setting the above variable, there is no other special

conﬁguration needed for supporting ACLs.

For a share supporting NT ACLs, the CIFS Server always tries to get, or

set, POSIX ACLs on the Unix ﬁle system. If the underlying ﬁle system

does not support POSIX ACLs, then the CIFS Server will use the Unix

ﬁle permissions. In such a case, the user will only be able to set or get the

three default ACEs (owner, group and everyone). Additional ACEs will

be ignored.

With version A.01.08 of the CIFS Server, the conﬁguration variable “acl

schemes” (exists in version A.01.07, and below) is not supported.

However, having this variable in the conﬁguration ﬁle will not hurt CIFS

Server operation.

The user is advised to remove or comment out occurrences of these

variables from the conﬁguration ﬁle (smb.conf) to prevent confusion.

IMPORTANT VxFS POSIX ACL ﬁle permissions only work when JFS 3.3 disk layout

version4 is installed on your system. For HP-UX 11.11, JFS 3.3 and disk

layout version4 is installed by default. Learn how to install JFS 3.3 on

HP-UX 11.0 in the HP JFS 3.3 and HP OnLineJFS 3.3 Release Notes

(MPN B3929-90007) located at www.docs.hp.com. Learn about installing

and upgrading disk layout versions in the HP JFS 3.3 and
