[SM-USERS] says "Unknown user or password incorrect"

[Peter <pe...@vi...>]

Hi,

I am trying to use SquirrelMail for the first time on my Redhat 6.2

I have IMAP server installed already as you can see below


[root@ns2 config]# telnet ns2.abcserver.com.hk 143
Trying 202.181.xxx.xxx...
Connected to ns2.abcserver.com.hk.
Escape character is '^]'.
* OK ns2.abcserver.com.hk IMAP4rev1 v12.264 server ready


But everytime I try to login to  SquirrelMail from the Web, it says:


Unknown user or password incorrect.

I select "UW" as the IMAP server type.

Is there something that I am missing?

Thanks.

Peter
