pre req warning libpam.so.0 is not found db2 10.5 issue

[peep]

OS linux 86
IIS 11.3.1
Db2 10.5

Before installation in the pre req checks I am getting the "warning" unable to find libpam.so.0 library db2 can not be installed.

I have sourced export LD_LIBRARY_PATH = /lib64:/lib:

and echoed the libpath is displayed.

I have find / -name libpam.so.0 and found the file in /lib64 and /lib too
I still dont understand why root is not able to find during installation.
DB2 10.5 pre req does not say any thing about 32 bit lib's ..
Any thoughts ?

Sys Adm installed 32 bit libs and that resolved the issue.
