Secure LDAP question

-

hi, have off-site application authenticating via secure ldap our ad domain controllers.  i have no clue how set up.  i did read through kb321051, raises more questions answers.  some of question are:

1) have other apps use ldap (unsecure).  will these break when install cert?

2) cert need installed on domain controllers, or one?  the configuration of external app allows point @ 1 ip address.

3) our domain mycompany.int.  it turns out .int domain protected.  usually it's not problem because never reference domain internet.  but i'm wondering if problem cert, dc's fqdns dc1.mycompany.int.  we of course have public domain - mycompany.com.  can make public dns records (dc1.mycompany.com) , use generating csrs?

4) finally, i'm wondering of hidden gotchas might be.  will else in ad break?  exchange?

thanks!

hi,

no. after enable ldap on ssl, dc still support normal ldap connection request.

you can enable ldap on ssl on 1 of dcs. why not enable ldap on ssl on dcs, encrypt dcs’ ldap communications.

this not question, since can request certificate custom subject alternative name (san). use of sans in server authentication certificates enables single certificate bound multiple names on single computer.

no, enable ldap on ssl (port 636), ldap service still listen port 389 , support normal ldap connection request.
