connecting as internal

I can connect to sqlplus as "internal" if I am logged on to UNIX as the oracle owner "oracle".
But I want to be able to logon to SQLPLUS as "internal" from another UNIX user.
I had the SA's set up a user and assigned him to the group "dba" (database group).
But I am having problems connecting :

SQL*Plus: Release 8.1.6.0.0 - Production on Tue Sep 4 14:56:13 2001
(c) Copyright 1999 Oracle Corporation. All rights reserved.
Enter user-name: internal
ERROR:
ORA-09925: Unable to create audit trail file SVR4 Error: 13: Permission denied
Additional information: 9925

How do I configure this on my system ?

Environment :
Oracle 8.1.6
Sun Sparc Solaris 5.8

Thanks in advance
