PAM/LDAP/IMAP Mail Delivery Failure

[Macgyver]

Hi All,

I am new to this list, but havent been able to find an answer to my
problem anywhere else as yet...

I have managed to get my redhat 9 box to authenticate via LDAP to a
Netware 6 box, however, when I try and send mail to an account on my
redhat box, it is returned with the error 'User Unknown'. The user
doesnt exist in the passwd file, but by issuing the getent passwd
command, the users details are displayed. I am able to open a telnet
session and login as the user, so I dont know where my problem might
be!

Has anyone else seen this problem before?

Any help would be greatly appreciated.

Thanks very much in advance,

Ben.
