For the previous directory server which we used we had not used any specific OIDs.Now for openLDAP i need to have a specific OID.
I have tried out all possible sample OIDs and have failed.........so now i have gone back to my usual  string instead of an OID,,,,like,,,
 

attributetype( ssarole-oid
 NAME 'ssarole'
 DESC 'This attribute defines the role'
 SYNTAX 'cis'
 MULTI-VALUE )

attributetype( ssaugtype-oid
 NAME 'ssaugtype'
 DESC 'This is Usergroup Type'
 SYNTAX 'cis'
 SINGLE-VALUE )
..................

...............

bjectclass( ssauser-oid
 NAME 'ssauser'
 DESC 'SSA User'
 SUP ssabase STRUCTURAL
 MAY( telephonenumber $ title $ mobile $ displayname $
  facsimiletelephonenumber $ preferredlanguage $ postaladdress $ c ) )

objectclass( supplier-oid
 NAME 'supplier'
 DESC 'SSA Supplier'
 SUP ssauser STRUCTURAL
 MUST businesspartnerid )

............

......................

but still the same problem persists.......that is either my schema file isnt being referred by server or an error saying

ldap_add: Invalid syntax (21)
        additional info: objectClass: value #1 invalid per syntax

KINDLY let me know as to how to get any OID for my purpose........or can i get away with having strings as OIDs.......

abd where else should i look into .
