NSS authentication issue in FIPS mode.

Hi ,

In FIPS mode I was using

"NSS FIPS 140-2 Certificate DB:mypassphrase" in /etc/ipsec.d/nsspassword and in my custom location.

But it is failing with the below error in logs:

Jun 27 12:36:11: authentication of "NSS FIPS 140-2 Certificate DB" failed Jun 27

12:36:11: FATAL: NSS initialization failure

I was using CentOS Linux release 7.4.1708 (Core) with libreswan-3.20-3.el7.x86_64.

Could you please help me to resolve this problem.
