saslauthd authentication problem

[Paul Wolstenholme]

I have saslauthd configured to use ldap. The uid have an "@". 
Authentication works using testsaslauthd:

Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=0 BIND 
dn="cn=Administrator,o=shoutout" method=128
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=0 BIND 
dn="cn=Administrator,o=shoutout" mech=SIMPLE ssf=0
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=0 RESULT tag=97 
err=0 text=
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=1 SRCH 
base="o=shoutout" scope=2 filter="(uid=paul at shoutout.ca)"
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=1 SRCH attr=dn
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=1 SEARCH RESULT 
tag=101 err=0 nentries=1 text=
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=2 BIND anonymous 
mech=implicit ssf=0
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=2 BIND 
dn="uid=paul at shoutout.ca,ou=users,ispmanDomain=shoutout.ca,o=shoutout" 
method=128
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=2 BIND 
dn="uid=paul at shoutout.ca,ou=users,ispmanDomain=shoutout.ca,o=shoutout" 
mech=SIMPLE ssf=0
Sep  3 10:38:36 localhost slapd[1248]: conn=118 op=2 RESULT tag=97 
err=0 text=


However, authentication failds whenusing imtest:
imtest -u 'paul at shoutout.ca' localhost

Sep  3 10:37:12 localhost slapd[1248]: conn=87 op=3 BIND anonymous

Sep  3 10:37:12 localhost slapd[1248]: conn=87 op=4 SRCH attr=dn
Sep  3 10:37:12 localhost slapd[1248]: conn=87 op=4 SEARCH RESULT 
tag=101 err=0 nentries=1 text=
Sep  3 10:37:12 localhost slapd[1248]: conn=87 op=5 BIND anonymous 
mech=implicit ssf=0
Sep  3 10:37:12 localhost slapd[1248]: conn=87 op=5 BIND 
dn="ispmanClientId=1,ispmanResellerId=2,ou=ispman,o=shoutout" 
method=128


I thought I may need a ldap_filter in my imapd.conf file:
ldap_filter: (uid=%u)

But, this does not seem to make any difference. Could someone point me 
in the right direction here. Thanks

Cheers,
Paul
