autobuild[sn-devel-144]: intermittent test failure detected

Wed Sep 5 06:18:18 UTC 2018

The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-09-05-0818/flakey.log

The failure seems to be in the "samba" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-09-05-0818/samba.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-09-05-0818/samba.stdout

The top commit at the time of the failure was:

    krb5-samba: interdomain trust uses different salt principal

    Salt principal for the interdomain trust is krbtgt/DOMAIN at REALM where
    DOMAIN is the sAMAccountName without the dollar sign ($)

    The salt principal for the BLA$ user object was generated wrong.

    dn: CN=bla.base,CN=System,DC=w4edom-l4,DC=base
    securityIdentifier: S-1-5-21-4053568372-2049667917-3384589010
    trustDirection: 3
    trustPartner: bla.base
    trustPosixOffset: -2147483648
    trustType: 2
    trustAttributes: 8
    flatName: BLA

    dn: CN=BLA$,CN=Users,DC=w4edom-l4,DC=base
    userAccountControl: 2080
    primaryGroupID: 513
    objectSid: S-1-5-21-278041429-3399921908-1452754838-1597
    accountExpires: 9223372036854775807
    sAMAccountName: BLA$
    sAMAccountType: 805306370
    pwdLastSet: 131485652467995000

    The salt stored by Windows in the package_PrimaryKerberosBlob
    (within supplementalCredentials) seems to be
    'W4EDOM-L4.BASEkrbtgtBLA' for the above trust
    and Samba stores 'W4EDOM-L4.BASEBLA$'.

    While the salt used when building the keys from
    trustAuthOutgoing/trustAuthIncoming is
    'W4EDOM-L4.BASEkrbtgtBLA.BASE', which we handle correct.
