hello ,
we're using LDAP for user authentication

I'm looking for a mechanism to automatically create a users home directory
when he logs in for the first time
Thanks,

The autodir package will do precisely that.  It's easy to setup too:

 
yum -y install autodir
 mkdir /u
   
 Edit /etc/sysconfig/auto
      AUTOHOME_HOME=/home/ldapusers
      AUTOHOME_OPTIONS="realpath=/u,level=2,skel=/etc/skel,mode=0700"home
   
    service autohome start
