I am sorry it has been very long time.
I ran the ldapsearch queries and the first two work and do display information. When I run it as a user from domainB then the users DN is returned but no pwdLastSet is returned...
first test..
dn: CN=user,DC=domain1,DC=com
pwdLastSet: 131565468314106532
second test..
dn: CN=user,DC=domain1,DC=com
