If you have reason to need PAM & NSS support for LDAP, yes, you need to 
be running 5.x, or else you might consider some Linux flavor as better 
serving your requirements.

Quite possibly, you won't encounter any problems.

BTW, if your only requirement driving the need for LDAP is mail users, 
one can set up Postfix and SASL to talk to LDAP, as well as configuring 
IMAP/POP to use LDAP-based accounts.  pam_ldap lets one have 
authenticated Unix-level users from LDAP accounts; if you don't need 
LDAP shell accounts, 4.x will be enough.

Do not install 5.1; it's too old, too many bugs.  5.2.1 is probably the 
most stable version available now, but there are significant bumps 
between it and the 5.3 betas now available which make upgrading to what 
will be 5-STABLE somewhat difficult.  If you've got the time to test 
the system, install a 5.3 beta.  If you can wait two weeks, 5.3 will 
become the preferred choice.
