That will work out of the box.

Make sure in ldap.attrmap you have

replyItem	Framed-IP-Address	radiusFramedIPAddress
replyItem	Framed-IP-Netmask	radiusFramedIPNetmask

**You can change those to whatever you store it as in ldap.

Then in the user, you put the IP.

dn: uid=someuser,ou=.....
radiusFramedIPAddress: 1.1.1.1
radiusFramedIPNetmask: 255.255.255.0

Then rlm_ldap, will look for an attribute of radiusFramedIPAddress and 
radiusFramedIPNetmask in ldap.  If it exists, it will send it back in the 
access-accept as a reply item.  If it doesn't exist, it won't send 
anything.

Did you try this yet?  If so and it isn't working for you, please send 
debug output (radiusd -X).
