ldapmodify returns Invalid Credentials

I have a peculiar problem with my SUN Directory Server 5.2 P4 deployment. I am able to login into the Admin console with the directory manager credentials. However when I using the same credentials for a ldapmodify operation it fails giving me a Invalid Credentials error.

$ ldapsearch -h <LDAPHost> -p <LDAPPort> -D "cn=Directory Manager" -w <password> -b uid=some_uid,ou=people,dc=example,dc=com objectclass=*

ldap_simple_bind: Invalid credentials

The access logs give a err=50 which means a Invalid password, but am using the right password.

I have mulitple instances of Directory Server running on this machine. Each Directory has a virtual IP assigned to it so that external clients can connect.

Thanks in Advance.
