1.183. samba3x

Updated samba3x packages that contain various bug fixes are now available for Red Hat Enterprise Linux 5.

Samba is a suite of programs used to share files, printers and other information between machines.

These packages contain fixes for the following bugs:

* the upstream Samba version in the samba3x packages distributed with the RHEA-2009:1399 update contained broken implementations of the Netlogon credential chain and SAMR access checks security subsystems. This prevented Samba from acting as a domain controller: Client systems could not join the domain; users could not authenticate; and systems could not access the user and group list. (BZ#506292)

* to modify the access control list for a file, WRITE_DAC and WRITE_OWNER access must be requested when the file is opened. When dos_filemode was enabled, these requests were not sent, so the access control list for a writeable file could not be changed. WRITE_DAC and WRITE_OWNER access are now requested when dos_filemode is enabled, so the access control list can be modified. (BZ#537165)

* samba3x was previously available only for AMD64 and Intel 64 architectures. It is now available for Itanium, PowerPC, IBM System z, x86, AMD64 and Intel 64 server and client variants. (BZ#547715)

* cifs.upcall could not determine the KRB5CCNAME environment variable, so it could not locate a Kerberos credential cache with a non-default name. This caused a 'required key not available' error when attempting to mount a Common Internet File System (CIFS) share. cifs.upcall now scans the /tmp directory for credential caches with non-default names, enabling users authenticated via pam_krb5 to use their tickets to mount CIFS. (BZ#548129)

* samba3x was previously only available as a technology preview for AMD64 and Intel 64 architectures. It is now supported for Itanium, PowerPC, IBM System z, x86, AMD64 and Intel 64 server and client variants.

Important: Clustered samba3x support is still a technology preview, and is available only on AMD64 and Intel 64 systems. (BZ#557921)

* Using the Windows Add Printer Wizard on samba3x-3.3.8 with CUPS configuration led to SMB panic. The printer would be installed correctly on CUPS. On Windows clients, an error message printed due to a Windows driver issue, installation failed, and SMB panic would be printed in the log. This patch resolves the SMB panic issue, allowing printers to be installed and removed from samba3x in Windows clients. (BZ#571778)

All previous samba3x technology preview packages must be removed before installing this new supported version of samba3x.

All users are advised to upgrade to these updated packages, which fix these bugs.
