[389-users] attribute to works same as a sequence number

[ghiureai]

Hi 389 List,

we have a need to use an existing attribute ( do not know wich 
one:nspentrydn ,nsbackendsufix) or create a new one use defined which 
will act similar as sequence number( integer values, incremental by 1 
,range values known) I understand we can not rely on nsUniqueId . Is 
there such an existing attribute in 389 , need to be unique , LDAP 
generate values with gap1 , range values can be controlled ?
