KB-2528: base.zonehier Failed to extend object

Authentication Service ,

Applies to: All versions of Centrify DirectControl on all platforms
 
Question:
 
The following messages can be seen in /var/log/messages running CDC 5.0.2 on a Red Hat Enterprise Linux 5:
 
adclient[3010]: WARN  <gpworker> base.zonehier Failed to extend object for CN=SRVARI11,CN=Computers,DC=csb,DC=local

adclient[1737]: INFO  <fd:25 PAMIsUserAllowedAccess2 > audit User 'action' is authorized

cda.dash[3406]: ERROR: Error in sending buffered stdin data. 
 
Answer:
 
These messages are safe to ignore as the computer objects are found when when the system traverses up the Zone-hierarchy.  

When searching the machine's computer object, DirectControl will search in the Computer Zone first, but since the computer object was created in the base Zone, it throws an exception: 
 
"No such object"
 
Then the hierarchical Zone will catch the exception and log that warning message.
 
Resolution:
 
This issue has been addressed in Suite 2013.
