When attempting to connect a remote enterprise console from a trusted ( 2way ) child sub domain you have an increase in token size because of the additional active directory information, causing problems when authenticating across domains.
The SEC remote console for example would fail to open throwing the following error:
Error in the Client Console Fatal Log:
Console Fatal: No sub-estates are assigned to this user ----- [outer exception] ----- -- error: 0x829E002C -- facility: Sophos Management Service Exception
First seen in Enterprise Console 4.5.0
The problem occurs because the workstation’s Kerberos token size exceeds 12,000 bytes. A parameter set to expand the size of the kerberos token resolves this issue.
To use this parameter:
Following formula to determine whether it is necessary to modify the MaxTokenSize value or not
This formula uses the following values:
In scenarios in which delegation is used (for example, when users authentication to a domain controller), Microsoft recommends to double the token size. Default token size is 12000.
