[horde] Login failed

[hardik]

Hello,

We have configured Webmail using Horde2.1+ IMP3.1+ PHP4.0.6 and qmail + LDAP + IMAP installation on two different Linux based servers. 

Everything is working fine except that it takes too long to authenticate a user and therefore many times it gives "Login failed for some reason. Most likely your username or password was entered incorrect", though the username and password r entered correctly.

Could u pl suggest how do we accelarate the login procedure. 

rgds,
