adclient: DEBUG util.except (cims::RPC) : NetLogon::authenticate failed: Buffer Overflow

If you running DirectControl 5.0.x and have addebug enabled then you may see below authenticate failed messages pretty much every 30 seconds in your /var/log/centrifydc.log file,

adclient[12219]: DIAG  <bg:updateOS> smb.rpc.netlogon authenticate - useAuthen3=1.

adclient[12219]: DEBUG <bg:updateOS> util.except (cims::RPC) : NetLogon::authenticate failed: Buffer Overflow (reference ../smb/rpcclient/netlogon.cpp:247 rc: -2147483643)

These messages are getting logged because your computer's samAccountName (in layman's terms hostname) is greater than 15 characters long on DirectControl 5.0.x. This has been fixed in 5.1.0 and in current latest version that is 5.1.2 at the time of writing this blog post.
