adduser命令出错

wangwelcome

操作过程和错误信息如下：
# adduser

Enter a login name for the new user (for example, john): sybase
Enter a UID for (sybase) [302]:
Enter a full name for (sybase): sybase
Enter a login group for (sybase) [users]: dba

Enter another group that (sybase) should be a member of.
(<Return>; only if none):
Enter a parent directory for (sybase) [/usr/users]: /home
The shells are:

/usr/bin/sh       /usr/bin/ksh      /bin/sh           /bin/ksh
/usr/bin/csh      /usr/bin/posix/sh /bin/csh

Enter a login shell for (sybase) [/bin/sh]:

Adding new user...
useradd: Incorrectly formed entry in passwd file, each entry should have 7 fields
Error, exiting useradd /usr/sbin/adduser. Check /etc/passwd.
＃

本来是可以增加用户的，但后来不知为什么就这样了。

吹拂的晨风

操作系统版本是多少？
还有，把/etc/passwd贴出来看看。
