kerberos and OpenLDAP

[themaoc () gmail com]

Hi
I must implement a network authentication services
My question is:
Wich it is the best option? I must use LDAP
for authentication in my network, or Mit Kerberos only.
my idea is use it same time both, It's better this? the level of the
security is far better?
I want to know if  it's better, kerberos with openldap or lDAP only,
or  the oppositte kerberos only
thanks
