I'm really banging my head on this one. I have a CentOS 6.1 running postfix/dovecot accessing a Windows 2008R2sp1 NFS share. In a test where the Windows server is a stand-alone file server, I can process email no problem. Once I try to do the same in a CLUSTERED 2008r2sp1 file server all that dovecot seems to be able to do is create the domain folder and account folder beneath that - not the cur, new, or tmp folders. Dovecot gives this error:
Error: chdir(/var/vmail/xxx.com/xxx/) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/vmail/xxx.com/xxx/, euid is not dir owner)
And in the shared folder I see the xxx.com directory and xxx subdirectory, but nothing inside the xxx subdirectory
The Windows NFS share has the following checked
NFS ADVANCED SHARING - No Server Authentication - Enable unmapped user access - Allow anonymous access UID 5000 GID 5000 (mapped to an AD domain user)
NFS SHARE PERMISSIONS - All Machines - Read-write - Root access allowed - ANSI
This share was set up the same on the standalone development server as it is in the server cluster. All file server systems are 2008r2sp1.
Any help or insightful questions would be greatly appreciated.
