[Samba] wbinfo-t fails but other wbinfo items works

i've migrated a debian box into ads, most people can work as they should,
some users eg which are not part of the domain can not authenticate
themself, the log says NT_STATUS_INVALID_COMPUTER_NAME .
After reading all the howtos i noticed that wbinfo -t doesn work, the output
#wbinfo -t
checking the trust secret via RPC calls failed
error code was NT_STATUS_INVALID_COMPUTER_NAME (0xc0000122)
Could not check secret

I assume that this might be the problem, i was able to join the samba box
fine, net getlocalsid works, kinit and klist also and i dont know why my
setup doesnt work.
My current debian versions are:
ii  krb5-config    1.7            Configuration files for Kerberos Version 5
ii  krb5-user      1.3.6-5        Basic programs to authenticate using MIT
ii  libkadm55      1.3.6-5        MIT Kerberos administration runtime
ii  libkrb53       1.3.6-5        MIT Kerberos runtime libraries
ii  libldap2       2.1.30-3       OpenLDAP libraries
ii  samba          3.0.20b-2+b1   a LanManager-like file and printer server
ii  samba-common   3.0.20b-2+b1   Samba common files used by both the server
ii  winbind        3.0.20b-2+b1   service to resolve user and group

My krb5.conf

         kdc = MYDOMAIN.COM
        admin_server = MYDOMAIN.COM

My smb.conf

    unix charset = ISO8859-15
    workgroup = INTERN
    realm = MYDOMAIN.COM
    security = ADS
    map to guest = Bad User
    password server = n.n.n.n
    passdb backend = smbpasswd, guest
    log level = 2
    log file = /var/log/samba/log.%U
    wins server = n.n.n.n
    ldap ssl = no
    panic action = /usr/share/samba/panic-action %d
    idmap uid = 10000-20000
    idmap gid = 10000-20000
    winbind use default domain = Yes
