How to a Add a Trusted Root Certificates to Solaris 11.4

Due to the following result by verifying PKI-Chain i think that a Root CA has to be added to the Solaris-Host. If i be right, how could that been done?

Solaris-Host~$ sudo openssl verify iuvo134.in.audi.vwg.crt_full

iuvo134.crt_full: DC = com, DC = abc DC = abcPKI, CN = abc-CA-ROOT-05

error 18 at 0 depth lookup:self signed certificate

OK

Solaris-Host~$ sudo openssl verify test123hsm42.crt_full

test123hsm42.crt_full: DC = com, DC = abc, DC = abcPKI, CN = abc-CA-ROOT-05

error 18 at 0 depth lookup:self signed certificate

OK

Solaris-Host~$
