The scope of information shared by an IdP is generally not quite as big as LDAP. At the most you'll get Fn, Ln, email and maybe a group name or two. If Okta has an LDAP service I'd have it configured in Jamf Pro to do the lookups for locations, etc. and keep SSO in play for authentication.
See here for more information.
Helps if I actually read the first sentence ;) . Double check your enrollment customization pane and ensure it's passing the necessary attributes i.e. name, email, etc. and that your username attribute in the SSO configuration was set to the proper attribute. You could also nuke and pave the SSO settings and the enrollment customization pane and try it again.
