This issue involved using Samba for AD authentication in order to access a local directory on an RHEL 2.6.9-67 server. The Linux machine (a vm on VMWare) joined the AD domain and was displayed as a "Domain Controller" in the Windows XP Find Computers tool rather than as a workstation/ server even though domain controller functionality has been explicitly disabled in smb.conf.
Initial system issues were resolved that included selinux AVC's that prevented access to the share and the following was added to smb.conf:
SELinux was disabled after initially being found in enforcing mode. Although it is possible to run selinux with Samba in this role, other functions on the machine were potentially affected by the presence of SELinux and its presence wasn't needed.
