A2A client fails on RHEL 8 using our RPM of A2A client (error while loading shared libraries: libidn.so.11)

Products

• CA Privileged Access Manager (PAM)

Issue/Introduction

We have created our own RPM to install the Linux A2A client of a previous release of PAM. Now we see users migrating to Linux RHEL 8 and after the A2A client is installed and connected to PAM they get this error. The application has a test script they run and here are the results.

Calling PAM using 'alias' and 'cache'

PAMalias          ==> XXXXX

PAMcache          ==> true

/opt/cloakware/catech/cspmclient/bin/cspmclient: error while loading shared libraries: libidn.so.11: cannot open shared object file: No such file or directory

Return from PAM...

I have had another user have this similar issue and here is their error.

We attempted and rec’d the following error:

 $: ksh MyScripts.ksh Account true
/opt/cloakware/catech/cspmclient_v.4.12.3/bin/cspmclient:

error while loading shared libraries: libidn.so.11: cannot open shared object file: No such file or directory
Return Code:

 We took a look at /usr/lib64 directory and the soft link is “libidn2.so.0 -> libidn2.so.0.3.6”:

User@SERVER [/usr/lib64]
$: ls -lrt libidn*
lrwxrwxrwx. 1      root root              16           Jun 10  2019        libidn2.so.0 -> libidn2.so.0.3.6
-rwxr-xr-x. 1         root root              162224 Jun 10  2019        libidn2.so.0.3.6

 

Environment

Release : 4.1

Cause

The required library libidn.so.11  was not on the system

~]# find / -name libidn.so.11

When running the following command we found the proper RPM containing this file was not installed

 ~]# rpm -qa |grep libidn
libidn2-2.2.0-1.el8.x86_64

Resolution

After installing  libidn-1.34-5.el8.x86_64.rpm the file was found and issue resolved.

~]# find / -name libidn.so.11
/usr/lib64/libidn.so.11

 ~]# rpm -qa |grep libidn
libidn-1.34-5.el8.x86_64
libidn2-2.2.0-1.el8.x86_64
