8.33 Changed Protected Password Database Format

The enhanced security user authentication proﬁles, originally stored in the

protected password ﬁles /tcb/files/auth/<a..z>/<username>, are

now stored by default in a database format. The convauth program, run for

an update installation, will convert existing ﬁles into the new format. Support

for the original format will be removed in a future release of Tru64 UNIX.

8.34 Audit_setup Script

The /usr/sbin/audit_setup script, used to conﬁgure auditing support,

will be retired in a future release of Tru64 UNIX. It will be replaced by

audit_config, an application in the SysMan suite that provides a full

graphical user interface.

8.35 VM Subsystem ubc_nfsloopback Variable Is

Obsolete

The /etc/sysconfigtab ubc_nfsloopback Virtual Memory (VM)

subsystem kernel conﬁguration variable is unnecessary, and has been

removed.

This conﬁguration variable was needed in some TruCluster conﬁgurations

with previous versions of Tru64 UNIX to avoid a recursion deadlock with

NFS loopback-mounted ﬁle systems. In those conﬁgurations, setting the

ubc_nfsloopback VM subsystem variable to 1 prevented the deadlock.

The ﬁle system code in Tru64 UNIX Version 4.0F has been modiﬁed to

prevent the deadlock which removes the need for the ubc-nfsloopback

variable.

If the variable is not removed from /etc/sysconfigtab, it will not

cause a problem. However, after the kernel is loaded by the ﬁrmware, the

console generates the following message to indicate that the variable is still

present in /etc/sysconfigtab:

sysconfigtab: attribute ubc_nfsloopback not in subsystem VM

8.36 libsecurity.a

libsecurity.a is the static archive form of the enhanced security library.

This form of libsecurity is no longer delivered in Tru64 UNIX.

Customers wishing to link against libsecurity should instead use the

shareable form, libsecurity.so.
