Login with NO PASSWORD - panic

Thu Nov 12 01:39:03 GMT 1998

Thanks, now logon with no password is working !

My current problem:
With no password set, there is no way to change it to something
other from the NT side ( CTRL-ALT_DEL -> "change password" ):

But with a password set there is a different behavior:
( And has maybe nothing to do with my original Problem ...)

User: smsadm
PW_old: test1234
PW_new: test4321

if you set the password via smbpasswd a. restart Samba:
"change password" is possible; logon with new password: ok !

But: Change password a second time:  "...wrong password" message on NT
In order to get "change password" working again you have to set
the password with smbpassword and restart Samba again!

Here is the smbpasswd entry for "smsadm": ( set with smbpaswd, PW:
"test1234"):
smsadm:103:624AAC413795CDC1FF17365FAF1FFE89:3B1B47E42E0463276E3DED6CEF349F93:

Entry after first( successful) password change ( to "test4321"):
smsadm:103:C959BEC57C2EF53BC2265B23734E0DAC:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:

Here is a ( hopefully ) important part of the logfile:
( This is the part during my first ( successfull ) password change !
