[Samba] mount: key has expired

[Horace]

Hello,

Distro: openSUSE 13.1
Samba Ver: 4.2.0pre1-GIT-a793ac0 (source compiled)
Client: Android 4.0.4 (Busybox)

According to on-line documents, this error "127 Key has expired" 
indicates that the user account password has been expired. However I am 
a bit puzzled because when I run this command:

$ pdbedit -L -v -u *********
