If your debug output (which you didn't provide) contains this line: 

WARNING: No "known good" password was found in LDAP.  Are you sure that 
the user is configured correctly? 

Then the likely problem is this line is missing from /etc/raddb/ldap.attrmap 

checkItem   Cleartext-Password      userPassword 

Here is what might be going on: 

Many authentication protocols (i.e. mschap) require that a clear text 
password be available to the radius server. Hopefully you have set the 
userPassword attribute for your users in your ldap server and protected 
it with an ACL. rlm_ldap will lookup the user in ldap and requests the 
attributes defined in /etc/raddb/ldap.attrmap labeled "checkItem" and 
then adds those attributes it found to the request. The attribute 
retrieved from ldap is the 3rd item on the line, the radius attribute 
which is added to the request is the 2nd item on the line. Thus what the 
above does is to add Cleartext-Password as a radius check item to the 
request with the value of the ldap attribute userPassword for the user. 

For reasons I do not understand the above line is missing from the 
default ldap.attrmap and this has tripped numerous people up. 

Alan: Is there a reason why ldap.attrmap omits the clear text password 
retrieval?
