[horde] 'remember password' configuration in horde?

[loki der quaeler]

is there a way to configure horde to allow users to remain logged in 
until they specifically choose to logout (so that if a user logs in 
today and sets the "remember me" option and doesn't click the 'logout' 
link; then tomorrow they attempt to use imp, for example, they would 
not be prompted again for their passowrd)?

thanks in advance,
loki
