Cyrus imap 2.3.11-xx with postfix 2.9.4

[Vladimir Klejch]

Hi

is portmap/rpcbind and ypbind running, look like problem of RPC and
because of them is the ypbind not runing correctly.

can you verify the functionality of ypages by :

id username
ypcat passwd |grep  username
getent passwd username


this should resolve the username and verify functionality of ypages


Cheers

                                         Kleo
