HP CIFS and Other HP-UX Kerberos
Applications Co-existence
Because the HP CIFS Server stores the Kerberos secret key in
/var/opt/samba/private/secrets.tdb by default, the standard CIFS
Kerberos configuration can only be used by HP CIFS Server users. If
other HP-UX applications use the /etc/krb5.keytab file, a mismatch of
keys occurs resulting in failure for CIFS or the other applications
depending upon which key is the latest. Moreover, HP-UX Internet
Services users cannot use system Kerberos libraries to access system
resources because of a mismatch in Kerberos libraries on the system.
The Internet Services (IS) suite utilizes its own Kerberos library set
which is delivered with the Internet Services product.
If you wish to use Kerberos in your network for other products as well as
HP CIFS Server, you may generate an /etc/krb5.keytab file from an
HP CIFS Server and configure HP CIFS Server to access the secret key
from the /etc/krb5.keytab file instead of the
/var/opt/samba/private/secrets.tdb file. This feature provides
Kerberos interoperability between HP CIFS Server users and HP-UX
Internet Services users. See Chapter 8, “Kerberos Support, on page 179,
for proper configuration.
