LDAP issue

Need assistance in resolving the below LDAP issue on Solaris 11. I am new to LDAP .

root@hrapps51:/var/svc/manifest# ldaplist -v
+++ database=NULL
+++ filter=objectclass=*
+++ template for merging SSD filter=%s
ldaplist: Object not found (LDAP ERROR (50): Insufficient access.)

What did you do to configure ldap authentication? Was it previously working? What say:

ldapclient list
svcs -v "*ldap/client*"

?
