Resolves: #191834
Summary: Clean up admin password in memory when it's freed
Description: (comment #5)
1) overwrote password string with '\0's.
2) psetCreate (psetc.c), psetCreateSSL (psetcssl.c)
Both has the similar code "passwd = bindPasswd; /* not to free bindPasswd */".
According to the comment, by setting bindPasswd to passwd, bindPasswd is not
supposed to be freed. But the current location does not stop it's being freed
since at that point bindPasswd is NULL and NULL is set to passwd. (Probably,
the path is not usually taken.)
