Configuring Authentication
==========================

To authenticate job submission from external users and VOs, HTCondor-CE can be configured to use
[built-in mapfiles](#built-in-mapfiles) or to make [Globus callouts](#globus-callout) to an external service like Argus
or LCMAPS.
The former option is simpler but the latter option may be preferred if your grid supports it or your site already runs
such a service.

Additionally, the HTCondor-CE service uses [X.509 certificates](#configuring-certificates) for SciTokens, SSL, and GSI

### GSI ###

To allow clients with GSI proxies with to submit jobs to your HTCondor-CE, add lines of the following format:

```
GSI /^<DISTINGUISHED NAME>$/ <USERNAME>
```

Replacing `<DISTINGUISHED NAME>` (escaping any `/` with `\/`) and `<USERNAME>` with the distinguished name of the
incoming certificate and the unix account under which the job should run, respectively.
VOMS attributes of incoming X.509 proxy certificates can also be used for mapping:

```
GSI /<DISTINGUISHED NAME>,<VOMS FQAN 1>,<VOMS FQAN 2>,...,<VOMSFQAN N>/ <USERNAME>
```

Replacing `<DISTINGUISHED NAME>` (escaping any `/` with `\/`), `<VOMSFQAN>` fields, and `<USERNAME>` with the
distinguished name of the incoming certificate, the VOMS roles and groups, and the unix account under which the job
should run, respectively.
For example, to map any certificate from the `GLOW` VO with the `htpc` role to the `glow` user, add the following line
to a `*.conf` file in `/etc/condor-ce/mapfiles.d/`:

```
GSI /.*,\/GLOW\/Role=htpc.*/ glow
```

Globus Callout
--------------

To use a Globus callout to a service like LCMAPS or Argus, you will need to have the relevant library installed as well
as the following HTCondor-CE configuration:

1. Add the following line to the top of `/etc/condor-ce/condor_mapfile`:

GSI /(.*)/ GSS_ASSIST_GRIDMAP

1. Create `/etc/grid-security/gsi-authz.conf` with the following content:

- For LCMAPS:

globus_mapping liblcas_lcmaps_gt4_mapping.so lcmaps_callout

- For Argus:

globus_mapping /usr/lib64/libgsi_pep_callout.so argus_pep_callout

Inserting IDTOKENs into the routed job's sandbox
------------------------------------------

If you want to insert IDTOKENS into the routed job's sandbox you can use the `SendIDTokens` route command, or
the `JOB_ROUTER_SEND_ROUTE_IDTOKENS` global configuration variable. Tokens
sent using this mechanism must be named and declared using the `JOB_ROUTER_CREATE_IDTOKEN_NAMES`
and [`JOB_ROUTER_CREATE_IDTOKEN_<name>`](https://htcondor.readthedocs.io/en/latest/admin-manual/configuration-macros.html#JOB_ROUTER_CREATE_IDTOKEN_%3CNAME%3E) configuration variables. Tokens whose names are declared in
the `JOB_ROUTER_SEND_ROUTE_IDTOKENS` configuration variable are sent by default for each route that does
not have a `SendIDTokens` command.

- **To declare IDTOKENS for inclusion in glide-in jobs** for the purpose of advertising to a collector
add something like the following to `/etc/condor-ce/config.d/99-local-ce-token.conf`:

JOB_ROUTER_CREATE_IDTOKEN_NAMES = name1 name2
JOB_ROUTER_CREATE_IDTOKEN_name1 @=end
sub = "[email protected]"
kid = "POOL"
lifetime = 3900
scope = "ADVERTISE_STARTD, ADVERTISE_MASTER, READ"
dir = "/etc/condor-ce/gltokens/name1"
filename = "ce_name1.idtoken"
owner = "owner1"
@end
JOB_ROUTER_CREATE_IDTOKEN_Name2 @=end
sub = "[email protected]"
kid = "POOL"
lifetime = 3900
scope = "ADVERTISE_STARTD, ADVERTISE_MASTER, READ"
dir = "/etc/condor-ce/gltokens/name2"
filename = "ce_name2.idtoken"
owner = "owner2"
@end

- **To insert one of the above IDTOKENS in the sandbox of a routed job**, include the token name in the `SendIDTokens` route
command like this.

SendIDTokens = "Name2"
!!! note "Route commands"
`SendIDTokens` is a route command, not a job attribute.
This means that you will not be able to manipulate it through
[transform verbs](writing-job-routes.md#editing-attributes) such as `EVALSET`.
**To add an IDTOKEN to a routed job in addition to the default tokens**, build a string containing the token name
along with the value of the global configuration variable like this.

SendIDTokens = "Name2 $(JOB_ROUTER_SEND_ROUTE_IDTOKENS)"

**You can use an attribute of the source job** to choose the IDTOKEN by writing an expression like this.

SendIDTokens = strcat( My.Owner, " $(JOB_ROUTER_SEND_ROUTE_IDTOKENS)")

It is presumed that the value of `My.Owner` above is the same as the `<name>` of an IDTOKEN and as the `owner` field
of that token. For instance, the Fermilab CE config uses the above `SendIDTokens` expression and
the following token declarations at the time of this guide.

JOB_ROUTER_CREATE_IDTOKEN_NAMES = fermilab3 osg
JOB_ROUTER_CREATE_IDTOKEN_fermilab3 @=end
sub = "[email protected]"
kid = "POOL"

The authentication method for submitting jobs to

a particular job (or modify existing jobs), you can look in
`/var/log/condor-ce/AuditLog`.

If GSI authentication was used, you'll see a set of lines like this:

Releases
========

HTCondor-CE 23 is distributed via RPM and are available from the following Yum repositories:

- [HTCondor stable and current channels](https://research.cs.wisc.edu/htcondor/downloads/)
- [Open Science Grid](https://opensciencegrid.org/docs/common/yum/)


Known Issues
------------

Known bugs affecting HTCondor-CEs can be found in
[Jira](https://opensciencegrid.atlassian.net/issues/?jql=project%20%3D%20HTCONDOR%20AND%20status%20not%20in%20(done%2C%20abandoned)%20and%20component%20%3D%20htcondor-ce%20and%20issuetype%20%3D%20bug)

Updating to HTCondor-CE 23
--------------------------

!!! note "Updating from HTCondor-CE < 6"
If updating to HTCondor-CE 23 from HTCondor-CE < 5, be sure to also consult the HTCondor-CE 6
[upgrade instructions](../v6/releases.md#500).

!!! tip "Finding relevant configuration changes"
When updating HTCondor-CE RPMs, `.rpmnew` and `.rpmsave` files may be created containing new defaults that you
should merge or new defaults that have replaced your customzations, respectively.
To find these files for HTCondor-CE, run the following command:

:::console
root@host # find /etc/condor-ce/ -name '*.rpmnew' -name '*.rpmsave'

HTCondor-CE 23 is very close in functionality yo HTCondor-CE 6.
As such, upgrading should be very easy.
