RedHat 8 install error in uniwhoami while loading libnsl.so.1

Issue/Introduction

We're trying out a new OS: RedHat 8.4.

When we try to install DUAS it, we have this error:

root@server# ./uniinstaller

 /tmp/silencieuse_du_as_6.10.61_redhat64/./tools/uniwhoami: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
Cannot get current user with "uniwhoami" command : stop here!

The Compatibility Matrix says that RedHat 8 is compatible with DUAS 6.10.*, so what is the problem?

Environment

Release : 6.10+

Component : Dollar Universe

OS: Redhat 8.x

Cause

Missing library libnsl.so.1 in the Operating System Redhat 8.x, necessary for uniwhoami system binary.

Resolution

The error indicates that the uniwhoami binary depends on the library libnsl.so.1 which seems not installed in the Redhat 8.x System

In order to fix this, simply install the libnsl library with the following command:

yum install libnsl

Additional Information

On a working Centos 8.4 this library exists as it comes with the baseos repository:

[root@SERVER~]# ldd /bin/whoami
        linux-vdso.so.1 (0x00007ffefc4c6000)

        /lib64/ld-linux-x86-64.so.2 (0x00007f7535687000)


[root@SERVER~]# yum provides libnsl.so.1
