When clicking the Authentication page on a new appliance, the page does not seem to load. However, if given enough time, the page will eventually load.
Even though LDAP or Radius is not configured, the appliance seems to be still making outbound calls to LDAP servers.
One of the calls being made is /sbin/dsldapad --groups=''
If this command is run independently, it will seem to hang for 10-15 minutes and then you'll get output like this:
[[email protected] ~]# /sbin/dsldapad --groups=
{"code": 404, "shortmsg": "LDAP Base DN Discovery failed with ldap://ldap_server:389", "details": {"params": ["/sbin/dsldapad", "--groups="]}}
