This is probably just fallout from the replica initialization failure.  
If a replica is never initialized, it will get a generation ID mismatch 
error when the master contacts it.

There was a bug in 389-ds-base that was fixed a while back where 
negative LDAP error codes were all printed as "System Error".  The -11 
is a connection error.  Here is how it is defined in /usr/include/ldap.h:

     #define LDAP_CONNECT_ERROR                              (-11)

It sounds like this connection error is occurring when it tries to 
initialize the replica.  It might help to enable replication level 
logging on the master, then trying to run ipa-replica-install again.  
The errors in the 389 DS errors log might point to the problem.  To 
enable replication level logging, you can perform the following 
operation with ldapmodify as "cn=Directory Manager":

------------------------------------------
dn: cn=config
changetype: modify
replace: nsslapd-errorlog-level
nsslapd-errorlog-level: 8192
------------------------------------------

When you are finished debugging the issue, don't forget to change the 
log level back to "0".
