It is an ASCII file containing one line for each user. Each field - ithin each line is separated from the next by a colon. Any entry - beginning with '#' is ignored. The smbpasswd file contains the - following information for each user: </para> - - <variablelist> - <varlistentry> - <term>name</term> - <listitem><para> This is the user name. It must be a name that - already exists in the standard UNIX passwd file. </para> - </listitem> - </varlistentry> - - <varlistentry> - <term>uid</term> - <listitem><para>This is the UNIX uid. It must match the uid - field for the same user entry in the standard UNIX passwd file. - If this does not match then Samba will refuse to recognize - this smbpasswd file entry as being valid for a user. - </para></listitem> - </varlistentry> - - - <varlistentry> - <term>Lanman Password Hash</term> - <listitem><para>This is the LANMAN hash of the user's password, - encoded as 32 hex digits. The LANMAN hash is created by DES - encrypting a well known string with the user's password as the - DES key. This is the same password used by Windows 95/98 machines. - Note that this password hash is regarded as weak as it is - vulnerable to dictionary attacks and if two users choose the - same password this entry will be identical (i.e. the password - is not "salted" as the UNIX password is). If the user has a - null password this field will contain the characters "NO PASSWORD" - as the start of the hex string. If the hex string is equal to - 32 'X' characters then the user's account is marked as - <constant>disabled</constant> and the user will not be able to - log onto the Samba server. </para> - - <para><emphasis>WARNING !!</emphasis> Note that, due to - the challenge-response nature of the SMB/CIFS authentication - protocol, anyone with a knowledge of this password hash will - be able to impersonate the user on the network. For this - reason these hashes are known as <emphasis>plain text - equivalents</emphasis> and must <emphasis>NOT</emphasis> be made - available to anyone but the root user. To protect these passwords - the smbpasswd file is placed in a directory with read and - traverse access only to the root user and the smbpasswd file - itself must be set to be read/write only by root, with no - other access. </para></listitem> - </varlistentry> - - - <varlistentry> - <term>NT Password Hash</term> - <listitem><para>This is the Windows NT hash of the user's - password, encoded as 32 hex digits. The Windows NT hash is - created by taking the user's password as represented in - 16-bit, little-endian UNICODE and then applying the MD4 - (internet rfc1321) hashing algorithm to it. </para> - - <para>This password hash is considered more secure than - the LANMAN Password Hash as it preserves the case of the - password and uses a much higher quality hashing algorithm. - However, it is still the case that if two users choose the same - password this entry will be identical (i.e. the password is - not "salted" as the UNIX password is). </para> - - <para><emphasis>WARNING !!</emphasis>.
