Release 2023.1 - Adbindproxy Release Notes

DirectControl for Samba is a proxy agent package that seamlessly integrates the Server Suite Agent for *NIX with open source Samba (referred to as stock Samba in this document), enabling the two products to share Active Directory user and group membership and to agree upon Unix identity attributes for Active Directory users. It is a proxy that passes identity management requests from Samba to the Server Suite Agent for *NIX.

Server Suite and its component services have been changed to use the new Delinea name and logo.

Known Issues

The following sections describe common known issues or limitations associated with this DirectControl for Samba release.

  • Limitations with stock Samba

    In previous releases of DirectControl for Samba, we modified the following in stock Samba for interoperability. Using stock Samba instead of Centrify Samba, you may see related issues.

    • Default Kerberos keytab location, KEYTAB_DEFAULT, from /etc/krb5.keytab to /etc/krb5/krb5.keytab on Solaris (SAMBA-890).
    • Default Kerberos cache location, CCNAME, from /tmp/krb5cc_%{uid} to /var/krb5/security/creds/krb5cc_%{uid}" on AIX (SAMBA-892).

  • Limitations with RHEL 7.2 PPC (SAMBA-965)

    If you are using 64bit Samba on a RHEL 7.2 PPC machine, you may have problem with adclient failed to use the 64bit tdb library come with 64 bit Samba. The symptom can be shown in the error message while trying to access samba server - “session setup failed: NT_STATUS_CANT_ACCESS_DOMAIN_INFO”.

    You need to install a 32bit tdb library, such as libtdb-1.3.6-2.el7.ppc.rpm in rhel-server-7.2-ppc64-dvd.iso, for adclient to work with, and you need to tell adclient where to get this library by adding a parameter “samba.libtdb.path: /usr/lib/libtdb.so.1” into centrifydc.conf, assuming the path to libtdb is /usr/lib/libtdb.so.1.
