For this command to work you will need a static map from the DMZ to the inside if the DMZ is on a lower security level.  

Do you have a command similiar to
static (inside,dmz) <dmz ip> <inside ip> <inside ip subnet mask>

If not, then you will need to add this translation to the inside.  


Also, you will need to apply the access-list to the interface using:
access-group DMZ_in in interface <name of the DMZ interface>

Hello,

You need the following three commands:

config t
static (inside,DMZ) tcp <dmz ip> 389 <inside ip> 389 netmask <inside ip subnet mask>
access-list DMZ_in extended permit tcp host SSL_VPN host DC2 eq 389
access-group DMZ_in in interface <name of the DMZ interface>


Thanks,
Craig
