POP3 authentication problems, IMS 5.2

All, I've successfully installed IMS 5.2 and have only run into one problem so far. The issue is: I have

mailAllowedServiceAccess: +all:all

set for all of my users and they are able to login to every service imap/http/smtp except for pop3.

Here is the error I get whilst trying to pop mail.

+OK ***.***.*** POP3 service (iPlanet Messaging Server 5.2 (built Feb 21 2002))

user <user>@<domain>

+OK Name is a valid mailbox

pass ********

-ERR Not authorized to login as specified user

I know the user info is correct as I am able to login via webmail and imap.

Has anyone run into this before? Below is a copy of my pop configs.

service.pop.allowanonymouslogin = no

service.pop.banner = "%h %p service (%P %V)"

service.pop.createtimestamp = 20020926194456Z

service.pop.creatorsname = "uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot"

service.pop.enable = yes

service.pop.idletimeout = 10

service.pop.maxsessions = 600

service.pop.maxthreads = 250

service.pop.modifiersname = "cn=msg-hoth,cn=iplanet messaging suite,cn=server group (2),cn=hoth.gte.net,ou=gte.net,o=netscaperoot"

service.pop.modifytimestamp = 20020930152334Z

service.pop.numprocesses = 1

service.pop.objectclass = nsmsgCfgPop ,top

service.pop.plaintextmincipher = 0

service.pop.popminpoll = 0

service.pop.port = 110

service.pop.sslusessl = no

Addendum.... I actually cannot use the SMTP authentication mechanism. So in the end, imap and http servers willl allow login, but pop3/smtp give the error:"535 5.7.8 Authorization Failuer (Not authorized to login as specified user)..."I appreciate anyone willing to help.
