PH40986: LOOKUPONLYFQNAMES REGISTRY KEY CAUSES ASYNC LICENSE ACQUISITION TO FAIL IN SOME MULTIPLE-WINDOWS-DOMAIN ENVIRONMENTS.

APAR status

• Closed as program error.

Error description

• In a multi-domain Windows environment, async license checkouts
  will fail under the following conditions:
  1. The albd account resides in one windows domain, for example
  "DOM1"
  2. The account for the user requesting a license (for example
  "evansmark") is in a different domain ("DOM2")
  3. The client host performing the license check has the
  following registry value present and set to 1:
  HKEY_LOCAL_MACHINE\Software\Wow6432Node\Atria\ClearCase\CurrentV
  ersion\LookupOnlyFQNames
  
  When the user attempts to perform ClearCase operations, the
  following will either be immediately observed, or will happen
  within 20 minutes of them accessing VOBs:
  - The user will see one or more "Background license checks are
  stalled. You do not have a license to run ClearCase"
  - The lad_server log will contain multiple errors stating that
  "Operation 'sysutil_user_to_sid' failed {username}." This log
  may only be easily accessible via the Windows Event viewer or by
  running "cleartool getlog lad" as the local "Administrator"
  user.
  

Local fix

• Set the
  HKEY_LOCAL_MACHINE\Software\Wow6432Node\Atria\ClearCase\CurrentV
  ersion\LookupOnlyFQNames value to 0 or delete the value. It is
  never set by default, and can only be set by editing the
  registry.
