I was trying to install samba client-3.0.10-2 in my machine but it asks for a couple of library files liblber-2.2.so.7 and libldap-2.2.so.7.
You are attempting to install the FC3 or rawhide version of the package. You could either install the FC2 version (current latest one is 3.0.10-1.fc2) or if you really need the very latest package, you could get the SRPM for it and rebuild it on your FC2 system to get an FC2-compatible package.
