Hi .

I upgraded my samba4 servers from 4.1.17 to 4.2.1 .

After upgrading ,  the samba4 servers becomed very slow and these error 
logs occured :

[2015/04/27 08:09:08.279400,  1] 
../source4/rpc_server/backupkey/dcesrv_backupke
y.c:1423(bkrp_do_retrieve_server_wrap_key)
  Unable to fetch value for secret 
BCKUPKEY_34847c15-efd9-4430-ba82-bf7d3160e9e1
, are we an undetected RODC?

This is the smb.conf of my server :

[global]
        bind interfaces only = yes
        interfaces = 10.5.1.26 127.0.0.1
        workgroup = TKT
        netbios name = DC
        realm = TKT.COM
        server role = active directory domain controller
        dns forwarder = 10.5.1.1
        ldap admin dn = cn=Administrator,cn=Users,dc=tkt,dc=com
        idmap_ldb:use rfc2307 = Yes
        server string = PDC server
        hostname lookups = no
        log level = 1
        log file = /var/log/samba4/samba.log
        max log size = 1024
        guest account = nobody
        wins support = yes
        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536
SO_SNDBUF=65536
        write cache size = 2097152
        getwd cache=yes
        min receivefile size = 16384
        os level = 80
[netlogon]
        path = /ap/samba4/var/locks/sysvol/tkt.com/scripts
        read only = No
[sysvol]
        path = /ap/samba4/var/locks/sysvol
        read only = No



I use this to compiled my smaba4 server :

./configure --prefix=/ap/samba4  \
            --download \
            --with-piddir=/var/run \
            --with-logfilebase=/var/log/samba4 \
            --with-ads     \
            --disable-iprint


Does anybody have any opinions or experience with my issue ?



thanks

Frank
