Re: replication problems

[Jaime Tomé Gomes Ventura <jaimeventura@ipp.pt>]

Thanks, Pierangelo.
Now i know how slurd works: It tries to replicate a change for each 
server listed on the  "replica" directives. So, since i have 2 replica 
directives(one per database) for each server, it would send the change 
request 2 twice for the same server.
A simple "work arround" is to write the  server name  with  all caps  in 
one  replica directive (for one database)  and  without caps in the 
olher replica directive(for the olher database).
Since  slapd  is  case sensitive, and DNS is not, slapd wont send the 
change request twice to the server, and the name resolution stil works.

   This drives me to another question: Why doent slurd check for  "name 
server" and "database baseDN" when sending a change request?
    I believe its not dificult to implement, it would easyer to 
understand and we wouldnt need "work arrounds".

Thanks, once again.
