I have implemented SSO/SAML for an On-Prem JIra Core 7 installation using Okta's instructions. When attempting the enable the provisioning section in Okta, I am prompted to test the API credentials to Jira. I receive an internal server error 500 for a response. Doing an internal curl command with the username/password, I am able to verify the credentials are valid.
Working with Okta, they have view my configuration and believe it to be set up correctly, according to their instructions. Has anyone else ran into this issue?
