Hi there,
I'm testing using freeradius to connect to Okta's LDAP interface but it's erroring out due to it apparently using a self signed cert:
rlm_ldap (ldap): Connecting to ldap://mycompany.ldap.okta.com:636
TLS certificate verification: Error, self-signed certificate in certificate chain
TLS: can't connect: error:0A000086:SSL routines::certificate verify failed (self-signed certificate in certificate chain).
But when I run this, it looks like the cert was issued by DigiCert:
* openssl s_client -connect mycompany.ldap.okta.com:636 -showcerts
subject=/C=US/ST=California/L=San Francisco/O=Okta, Inc./CN=*.ldap.okta.com
issuer=/C=US/O=DigiCert Inc/CN=DigiCert Global G2 TLS RSA SHA256 2020 CA1
Obviously getting mixed messages here but does anyone have any guidance?
Thanks!
