Login problem when using LDAP based authentication

[raghu_at_work]

Hi,

I am running CVS on a Linux Redhat 7.1 box. I am using xinetd to 
offer the cvspserver service. We have disabled telnet access to the 
users on this machine.
For user information and passwords, this machine connects to an 
external LDAP server.

For authentication, the 'cvs login' works if I login as a local user, 
but If I use LDAP account, the login fails and gives the following 
error.

cvs [login aborted]: connect to 192.168.2.5(192.168.2.5):2401 failed: 
Connection refused

Can anybody please help me out.

Thanks
