Generally the whole purpose of using a directory server (LDAP) is to benefit from centralized and consistent configuration and authentication. As such, most setups use the same user base for everything (in your case IMAP access and shell logins). You just need to point each service (login and IMAP) to your directory and filter based on the existence of certain attributes. For example, only users with the objectclass=mailRecipient would be allowed to login to your IMAP mail store. This can easily be accomplished through the authentication system of your IMAP software (one that supports LDAP authentication).
