authenticate users on a ldap

[Jens Christian Madsen]

Hi am i total greenhorn on imp/horde but it got everything I need.

is it possible to make IMP check username/password on an LDAP catalog to
verify if they are users? and even to ceck for a cookie and then skip logon
screen? (they allready logged on somewhere else!)

I ask this because I got to solve a problem where users logon. and then they
can move form on service to another one. without the need of retype there
name/password.
