Thanks for your quick input Daniel.

I have some questions regarding what you said (and where I'm
currently at with replication)

I'm confused about this.  Am I adding a user object to the DB? 
Do you have an example of doing this (I am a newcomer to LDAP).

-C -> chase is supposed to (I think) work but instead I get some
confusing results.  I do the ldapmodifies on the slave and if
the entry is in the master I get "Already exists" (note it
doesn't exist on the slave) see below.  If the entry isn't on
the master I get "Insufficient access".

Leaf nodes not present on master, ldapmodify chase on slave,
result:

ldapmodify -a -c -x -C -D 'cn=Manager,dc=SharemediaTest,dc=com'
-W -f TwoBethesdaEntries.ldif 
Enter LDAP Password: 
adding new entry "cn=Bethesda, cn=MD, dc=SharemediaTest, dc=com"
ldap_add: Already exists

ldif_record() = 68
adding new entry "cn=B1 A-1 Cafe, cn=Bethesda, cn=MD,
dc=SharemediaTest, dc=com"ldap_add: Insufficient access
	additional info: no write access to parent

ldif_record() = 50
adding new entry "cn=B2 Aangan Indian Restaurant, cn=Bethesda,
cn=MD, dc=SharemediaTest, dc=com"
ldap_add: Insufficient access
	additional info: no write access to parent


Leaf nodes present on master (but not client) ldapmodify with
chase:

ldapmodify -a -c -x -C -D 'cn=Manager,dc=SharemediaTest,dc=com'
-W -f TwoBethesdaEntries.ldif 
Enter LDAP Password: 
adding new entry "cn=Bethesda, cn=MD, dc=SharemediaTest, dc=com"
ldap_add: Already exists

ldif_record() = 68
adding new entry "cn=B1 A-1 Cafe, cn=Bethesda, cn=MD,
dc=SharemediaTest, dc=com"ldap_add: Already exists

ldif_record() = 68
adding new entry "cn=B2 Aangan Indian Restaurant, cn=Bethesda,
cn=MD, dc=SharemediaTest, dc=com"
ldap_add: Already exists

Thanks for the tip- I've seen a lot of info on this list. 
Unfortunately, many times when someone has the same question I
do the post doesn't have an answer.

For instance I'm having the same problem as the following posts:

Basically:  If I make changes to the master slapd makes a log
and slurpd eats it then slurpd copies the log of work to be done
to a temp directory.  No errors are generated but changes are
only made to the master.  Furthermore if I -d 65535 the slurpd
process (enable all debugging) I get the following info:

Also the user's admin guide states that if a port is omitted
from the replica directive the standard 389 is assumed but when
I first did debugging I noticed the master assumed port 0.
