Greetings, I am very new to Samba and at my job I have been tasked with the making Samba passwords sync with RACF(running on a mainframe) passwords . I am running Redhat Linux 3.0 ES on a Dell box . I searched Samba.org but did not find anything on Samba and RACF . My main questions are : 1. Can this be done? The version of Samba I am running is 3.0.14 2. the version of Redhat is : Linux 2.4.21-4.EL #1 Fri Oct 3 18:13:58 EDT 2003 i686 i686 i386 GNU/Linux ------- If someone has done this or can tell me where to start I would appreciate it . Thanks, Sim
