Certificates troubleshooting

Hi! we are trying to implement a SSL VPN connection through Global Protect using certificates from our own CA. We imported the root, intermediate and server certificate, but after configuring the portal we see an warning after commit: " cannot find complete certificate chain for certificate.." , and we don't see any traffic from the Palo Alto trying to validate the certificate. I would like to know if there is any way to see from CLI the source of this error, in order to troubleshoot the problem.

Thanks!

When a certificate is imported into the firewall which is signed by an intermediate certificate ,firewall strips of the intermediate certificate attached and to the certificate and will show this warning.

This bug 47565 has been fixed with OS-5.0.3.

Following workaround has worked for users but I have tested it.

Export the config, modify the cert line:

change

ca no;

to

ca yes;

Save and import.

When you import that chain of CA servers the data must be in a single file which you then import.

However I dont remember if the top-CA should be first in this file or last.

I received a similar warning as OP when importing a certificate. Running PAN-OS 5.0.2

PA engineers, please note, in my scenario the error message has a misspelling which may result in difficulty finding a solution in your knowledge base.

warning: cannot find complete certficate chain for certificate

The first use of the word "certificate" is missing an "i".

I had imported only intermediate certificate.

I have seen this error message.

Will I have to import root and intermediate certificates??

Do I need other something??
