McGraw Hill's Understanding and Deploying LDAP Directories with the

the new one (saw it on Amazon) look like it is blue.
http://www.amazon.com/exec/obidos/tg/detail/-/0672323168/qid=1075222069//ref=sr_8_xs_ap_i9_xgl14/102-1748758-6408160?v=glance&s=books&n=507846

http://www.amazon.com/exec/obidos/tg/detail/-/020178792X/qid=1075222069//ref=sr_8_xs_ap_i6_xgl14/102-1748758-6408160?v=glance&s=books&n=507846
