SASL authentication, user not found

Hi, I've just managed to get cyrus SASL and OpenLDAP talking to each other
properly and I'm a little confused as to what I've done wrong.

Following is a dump of relevant information;
**************
[root@LSiaB ldif]# sasldblistusers
user: testuser realm: LSiaB mech: PLAIN
user: testuser realm: LSiaB mech: CRAM-MD5
user: testuser realm: LSiaB mech: DIGEST-MD5

[root@LSiaB ldif]# sasldblistusers2
testuser@LSiaB: userPassword

[root@LSiaB ldif]# ldapsearch -x -b 'o=lsiab.lan' '(objectclass=*)'
# lsiab.lan
dn: o=lsiab.lan
o: lsiab.lan

# admin, lsiab.lan

# test, lsiab.lan

# testuser, test, lsiab.lan

Cyrus SASL versions
-------------------
cyrus-sasl-gssapi-2.1.10-2
cyrus-sasl-2.1.10-2
cyrus-sasl-md5-2.1.10-2
cyrus-sasl-plain-2.1.10-2

OpenLDAP versions
-----------------
openldap-servers-2.1.8-1
openldap-clients-2.1.8-1
openldap-2.1.8-1
**************
I'm wondering if I'm using the correct name to log in, the correct username
in the sasldb and the correct sasl-regexp.

In a recent post to the mailing list I saw that 

>> sasl-regexp 
>> 	"uid=(.*),cn=digest-md5,cn=auth" 
>> 	"ldap:///dc=rtp,dc=KiNETWORKS,dc=com??sub?cn=$1";

may work better, would this help in my situation??

Thanks in advance Karl
