When created an account for a user and when he logged in, a message "-sh: default: cannot execute" d

Hi all,

Problem description : System is running on Solaris 9 and after applied kernel patches to 122300-67, everything seems okay unless create user account.

1). When created an account for a user and when he logged in, a message "-sh: default: cannot execute" displayed

2). Customer using the KVM login this account failed, but login another user account is fine.   

We've checked the following, but still no any idea: 

- As this looks like permission problem. We've checked whether the parent directories have read & execute permissions and checked the user home directory privilege of this account. (w.r.x permission), like 700 or 755. 

- Also check the /etc/passwd, /etc/shadow, /etc/group without *LK*  (lock account)
