Probably the same reason.

Are you positive that the AD credentials you entered in the portal are correct?

Unlike ATA in AATP we have no "test" for them in the UI.

Make sure the username, domain and password are correct.

What is the OS version you are running on?

Also, the output of

nltest /DSGETDC: && nltest /DOMAIN_TRUSTS

on both forests might help, but you might want a support case to share this info with us , the forum is not ideal for this...

  Are you 100% sure about the trust setup?
  
  Currently we only support full two way trust, or full one way trust where the AATP AD account that you have set is coming from the trusted forest.
  
  So far I have only seen this error (ErrorCode=82) in cases where the trust was not such but some other type.
  
  Can you double check it?
  
  Also, make sure the account details (username, password) supplied to AATP are correct.

    Hi Eli,
    Everything is inside one of the domains. ATP user is from this domain too. Second domain is not involved in the process.
