|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>dlog</B> command obtains DCE credentials for the issuer from the
|
||
|
|
DCE Security Service in the cell named by the <B>-cell</B> argument, and
|
||
|
|
stores them on the AFS client machine on which the user issues the
|
||
|
|
command. The AFS/DFS Migration Toolkit Protocol Translator processes
|
||
|
|
running on machines in the DCE cell accept the credentials, which enables the
|
||
|
|
user to access the DCE cell's filespace from the AFS client. The
|
||
|
|
user's identity in the local file system is unchanged.
|
||
|
|
<P>If the issuer does not provide the <B>-principal</B> argument, the
|
||
|
|
<B>dlog</B> command interpreter uses the user name under which the issuer
|
||
|
|
is logged into the local file system. Provide the DCE password for the
|
||
|
|
appropriate user name. As with the <B>klog</B> command, the
|
||
|
|
password does not cross the network in clear text (unless the issuer is logged
|
||
|
|
into the AFS client from a remote machine).
|
||
|
|
<P>The credentials are valid for a lifetime equivalent to the smallest of the
|
||
|
|
following, all but the last of which is defined by the DCE cell's
|
||
|
|
Security Server:
|
||
|
|
<UL>
|
||
|
|
<P><LI>The maximum certificate lifetime for the issuer's DCE account
|
||
|
|
<P><LI>The maximum certificate lifetime for the <B>afs</B> principal's
|
||
|
|
DCE account
|
||
|
|
<P><LI>The registry-wide maximum certificate lifetime
|
||
|
|
<P><LI>The registry-wide default certificate lifetime
|
||
|
|
<P><LI>The lifetime requested using the <B>-lifetime</B> argument
|
||
|
|
</UL>
|
||
|
|
<P>If the previous maximum certificate lifetime values are set to
|
||
|
|
<B>default-policy</B>, the maximum possible ticket lifetime is defined by
|
||
|
|
the default certificate lifetime. Refer to the DCE vendor's
|
||
|
|
administration guide for more information before setting any of these
|
||
|
|
values.
|
||
|
|
<P>The AFS Cache Manager stores the ticket in a credential structure
|
||
|
|
associated with the name of the issuer (or the user named by the
|
||
|
|
<B>-principal</B> argument. If the user already has a ticket for
|
||
|
|
the DCE cell, the ticket resulting from this command replaces it in the
|
||
|
|
credential structure.
|
||
|
|
<P>The AFS <B>tokens</B> command displays the ticket obtained by the
|
||
|
|
<B>dlog</B> command for the server principal <B>afs</B>, regardless of
|
||
|
|
the principal to which it is actually granted. Note that the
|
||
|
|
<B>tokens</B> command does not distinguish tickets for a DFS<SUP>TM</SUP>
|
||
|
|
File Server from tickets for an AFS File Server.
|
||
|
|
<P><STRONG>Options</STRONG>
|
||
|
|
<DL>
|
||
|
|
<P><DT><B>-principal
|
||
|
|
</B><DD>Specifies the DCE user name for which to obtain DCE credentials. If
|
||
|
|
this option is omitted, the <B>dlog</B> command interpreter uses the name
|
||
|
|
under which the issuer is logged into the local file system.
|
||
|
|
<P><DT><B>-cell
|
||
|
|
</B><DD>Specifies the DCE cell in which to authenticate. During a single
|
||
|
|
login session on a given machine, a user can authenticate in multiple cells
|
||
|
|
simultaneously, but can have only one ticket at a time for each cell (that is,
|
||
|
|
it is possible to authenticate under only one identity per cell per
|
||
|
|
machine). It is legal to abbreviate the cell name to the shortest form
|
||
|
|
that distinguishes it from the other cells listed in the
|
||
|
|
<B>/usr/vice/etc/CellServDB</B> file on the local client machine.
|
||
|
|
<P>If the issuer does not provide the <B>-cell</B> argument, the
|
||
|
|
<B>dlog</B> command attempts to authenticate with the DCE Security Server
|
||
|
|
for the cell defined by
|
||
|
|
<OL TYPE=1>
|
||
|
|
<P><LI>The value of the environment variable AFSCELL on the local AFS client
|
||
|
|
machine, if defined. The issuer can set the AFSCELL environment
|
||
|
|
variable to name the desired DCE cell.
|
||
|
|
<P><LI>The cell name in the <B>/usr/vice/etc/ThisCell</B> file on the local
|
||
|
|
AFS client machine. The machine's administrator can place the
|
||
|
|
desired DCE cell's name in the file.
|
||
|
|
</OL>
|
||
|
|
<P><DT><B>-password
|
||
|
|
</B><DD>Specifies the password for the issuer (or for the user named by the
|
||
|
|
<B>-principal</B> argument). Using this argument is not
|
||
|
|
recommended, because it makes the password visible on the command line.
|
||
|
|
If this argument is omitted, the command prompts for the password and does not
|
||
|
|
echo it visibly.
|
||
|
|
<P><DT><B>-servers
|
||
|
|
</B><DD>Specifies a list of DFS database server machines running the Translator
|
||
|
|
Server through which the AFS client machine can attempt to
|
||
|
|
authenticate. Specify each server by hostname, shortened machine name,
|
||
|
|
or IP address. If this argument is omitted, the <B>dlog</B> command
|
||
|
|
interpreter randomly selects a machine from the list of DFS Fileset Location
|
||
|
|
(FL) Servers in the <B>/usr/vice/etc/CellServDB</B> file for the DCE cell
|
||
|
|
specified by the <B>-cell</B> argument. This argument is useful for
|
||
|
|
testing when authentication seems to be failing on certain server
|
||
|
|
machines.
|
||
|
|
<P><DT><B>-lifetime
|
||
|
|
</B><DD>Requests a ticket lifetime using the format
|
||
|
|
<VAR>hh</VAR><B>:</B><VAR>mm</VAR>[<B>:</B><VAR>ss</VAR>]
|
||
|
|
(hours, minutes, and optionally a number seconds between 00 and 59).
|
||
|
|
For example, the value <B>168:30</B> requests a ticket lifetime of 7
|
||
|
|
days and 30 minutes, and <B>96:00</B> requests a lifetime of 4
|
||
|
|
days. Acceptable values range from <B>00:05</B> (5 minutes)
|
||
|
|
to <B>720:00</B> (30 days). If this argument is not provided
|
||
|
|
and no other determinants of ticket lifetime have been changed from their
|
||
|
|
defaults, ticket lifetime is 10 hours.
|
||
|
|
<P>The requested lifetime must be smaller than any of the DCE cell's
|
||
|
|
determinants for ticket lifetime; see the discussion in the preceding
|
||
|
|
<B>Description</B> section.
|
||
|
|
<P><DT><B>-setpag
|
||
|
|
</B><DD>Creates a process authentication group (PAG) in which the newly created
|
||
|
|
ticket is placed. If this flag is omitted, the ticket is instead
|
||
|
|
associated with the issuers' local user ID (UID).
|
||
|
|
<P><DT><B>-pipe
|
||
|
|
</B><DD>Suppresses any prompts that the command interpreter otherwise produces,
|
||
|
|
including the prompt for the issuer's password. Instead, the
|
||
|
|
command interpreter accepts the password via the standard input stream.
|
||
|
|
<P><DT><B>-help
|
||
|
|
</B><DD>Prints the online help for this command. All other valid options
|
||
|
|
are ignored.

<P><STRONG>Output</STRONG>
|
||
|
|
<P>If the <B>dlog</B> command interpreter cannot contact a Translator

Server, it produces a message similar to the following:
