I realize that I'm coming to this thread very late. I'm not an AIX man either but I've had a few confrontations with accessing MS-shares from Unix/Linux/whatever boxes. Before I post anymore, I must state that everything I write is purely generic Unix speak and NOT AIX specific.

1. Usually, the MS admin creates a share (hidden or visible) with the Unix users username and password. Then the Unix/Linux user simply logs in and his password is transmitted to the MSbox to access the share.
2. The Unix admin installs an SMB client and declares (adds) the specific Unix user as an SMB user.
3. At this point you would expect a connection to the MS share to work BUT IT Doesn't. The reason is that the SMB password to be transmitted to the MSbox has to be hashed in (typically) '/var/smb/smbpasswd' but when you look in there, that users hashed record is not there. However, now the Unix box is aware that the user is an SMB client user, if the sysadmin (or the user themselves) resets that user's password with the 'passwd' command (even if it's set to what is was already), the hash will be put in '/var/smb/smbpasswd' file. It miraculously appears. Until that hash is in the smbpasswd file there isn't a hope in hell of it working.

As I said, this may or may not be relevant. Others subscribed to this thread may know better but I just thought I'd chip in with that.

Best of luck.

pam_smb_passwd

pam_smb_passwd(5)					Standards, Environments, and Macros					 pam_smb_passwd(5)

NAME

       pam_smb_passwd - SMB password management module

SYNOPSIS

       pam_smb_passwd.so.1

DESCRIPTION

       The  pam_smb_passwd  module enhances the PAM password management stack. This functionality supports the changing or adding of SMB passwords
       for local Solaris users. The Solaris CIFS server uses SMB passwords to authenticate connected  Solaris  users.  This  module  includes  the
       pam_sm_chauthtok(3PAM) function.

       The pam_sm_chauthtok() function accepts the following flags:

       PAM_PRELIM_CHECK

	   Always returns PAM_IGNORE.

       PAM_SILENT

	   Suppresses messages.

       PAM_UPDATE_AUTHTOK

	   Updates  or	creates  a  new CIFS local LM/NTLM hash for the user that is specified in PAM_USER by using the authentication information
	   found in PAM_AUTHTOK. The LM hash is only created if the smbd/lmauth_level property value of the smb/server service	is  set  to  3	or
	   less. PAM_IGNORE is returned if the user is not in the local /etc/passwd repository.

       The following options can be passed to the pam_smb_passwd module:

       debug

	   Produces syslog(3C) debugging information at the LOG_AUTH or LOG_DEBUG level.

       nowarn

	   Suppresses warning messages.

FILES

       /var/smb/smbpasswd

	   Stores SMB passwords for Solaris users.

ERRORS

       Upon successful completion of pam_sm_chauthtok(), PAM_SUCCESS is returned. The following error codes are returned upon error:

       PAM_AUTHTOK_ERR

	   Authentication token manipulation error

       PAM_AUTHTOK_LOCK_BUSY

	   SMB password file is locked

       PAM_PERM_DENIED

	   Permissions are insufficient for accessing the SMB password file

       PAM_SYSTEM_ERR

	   System error

       PAM_USER_UNKNOWN

	   User is unknown

ATTRIBUTES

       See the attributes(5) man page for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Committed 		   |
       +-----------------------------+-----------------------------+
       |MT Level		     |MT-Safe with exceptions	   |
       +-----------------------------+-----------------------------+

NOTES

       The interfaces in libpam(3LIB) are MT-Safe only if each thread within the multi-threaded application uses its own PAM handle.

       The pam_smb_passwd.so.1 module should be stacked following all password qualification modules in the PAM password stack.
