Search fields in admin panel

[MoonWolf]

I would like to search in admin panel for users that are not in
django's database. They are accessed through LDAP, only uid's are in
database. Other data are accessed through properties, for example:

@property
def full_name(self):
return unicode(_ldap.search_s("ou=People,ou=Main,o=company",
ldap.SCOPE_ONELEVEL, "uidNumber=%s" % self.uidNumber,
["cn"])[0][1]["cn"][0], "utf-8")

And of course it's not possible because only real fields are
allowed in "search_fields".

I found some advices here: http://stackoverflow.com/questions/6752388/django-customize-adminmodel-view
and here:
http://stackoverflow.com/questions/3729023/django-admin-search-fields-with-model-property

But - to be honest - i don't know where to start. Could you point me
to some documentation or even solution? TIA.
