Team,
Unable to login to DPA via Active Directory Account, but configure AD/LDAP via users & Contacts getting succeeded so please help to fix it.
99.99% of the time when we get this it is something with the environment in which DPA is trying to authenticate against. Just because the wizard succeeded, doesn't necessarily mean that things are configured correctly - just that syntactically, you got inputs correct.
After you integrate with AD, are you able to search for known security groups?
You will likely want to open a ticket with support on this one as they'll want to collect logs to see what errors you are getting.
