Encountering LW_ERROR_LDAP_INSUFFICIENT_ACCESS [LW_ERROR_LDAP_INSUFFICIENT_ACCESS] on Open Likewise

I was trying to join my Linux Box to an MS Active Directory Domain using Likewise Open from Likewise. Although I have permission to join computers to MS Active Directory domain but somehow once I use the command

# ./domainjoin-cli --logfile logfile join --ou my_OU my_AD_Domain Administrators

From the Trace Stacks that comes out was

Stack Trace:

But somehow I suspect I may not have permission to set certain attributes (such as Description) on the computer account
