              Hey Mark.

                
              Thanks for your answer.

              
              Just to be sure, you say this entry is regularly updated,
              but when I try to ldapsearch it, I cannot find it :

            
            ###

            ldapsearch -x -D "cn=Directory Manager" -h <IPA
            SERVER> -p 389 -W -b "cn=repl keep alive 6,dc=mydomain"

            ###

            
          Result :

            ###

            # extended LDIF

            #

            # LDAPv3

            # base <cn=repl keep alive 6,dc=mydomain> with scope
            subtree

            # filter: (objectclass=*)

            # requesting: ALL

            #

            
            # search result

            search: 2

            result: 32 No such object

            matchedDN: dc=mydomain

            
            # numResponses: 1

            ###

            
          Maybe my ldapsearch is bad ?

          
    Its an ldapsubentry, so you need to search for the exact DN and do a
    "base" search.  So, you just need to add "-s base" to your
    ldapsearch from above:

    
    ldapsearch -x -D "cn=Directory Manager" -h <IPA SERVER> -p 389
    -W -b "cn=repl keep alive 6,dc=mydomain" -s base

    
    Regards,

    Mark

    
          Best regards.

                            Hello.

                              
                            I'm using FreeIPA and I have 4 masters which
                            replicates to each others.

                            
                          On all the masters, I can see the following
                          message from time to time :

                          ###

                          NSMMReplicationPlugin - replication keep alive
                          entry <cn=repl keep alive 6,dc=mydomain>
                          already exists

                          ###

                          
                        I don't really understand this message in fact.
                        May you explain it to me please ?

                      
               This message is harmless and can be ignored.  The
              replication plugin is just trying to add the "keep alive"
              entry, but it already exists(which is fine).  This ticket
              is what introduced the "keep alive" entry:

              
              https://fedorahosted.org/389/ticket/48266

              
              Basically it is an entry that is periodically updated to
              avoid replicas from becoming stale - which can lead to
              replication permanently breaking, and require a
              re-initialization.

              
              Is the message being logged too often?  Perhaps this
              message can be moved to the "replication" logging section,
              instead of being logged by default?  Can you can open a
              new ticket to have that investigated if you would like.
