N2SNUserTools 0.1.1

Installation Instructions

In order to install N2SNUserTools the GSSAPI python module is needed. This requires the libkrb5-dev package to be installed. This can be installed on debian derivatives by:

sudo apt-get install libkrb5-dev

Having installed these dependencies, the package can be installed in the usual pythonic way:

python setup.py install

Configuration

The user scripts rely on a configuration INI file which can be instaled either in /etc/n2sn_tools.conf or in the users home folder in ~/.config/n2sn_tools.conf

The format of the config file is:

[common]
server = addressbook.bnl.gov
user_search = "ou=cam - users,ou=cam,dc=bnl,dc=gov"
group_search = "ou=n2sn,ou=ccm,dc=bnl,dc=gov"
default_instrument = csx

[csx]
name = csx
user_group = n2sn-instusers-csx
staff_group = n2sn-inststaff-csx

Searching for Users

To search for valid users, use the n2sn_find_user command. For example to search for all the Stuarts:

❯ n2sn_search_user --givenname stuart
+------------------+-----------+-------------------+------------+-------------------+-----------+
| Name             | ITD Login | E-Mail            | Department | Life/Guest Number | Can Login |
+------------------+-----------+-------------------+------------+-------------------+-----------+
| Myers, Stuart F  | smyers    | smyers@bnl.gov    |     PS     |       22850       |    True   |
| Wilkins, Stuart  | swilkins  | swilkins@bnl.gov  |     PS     |       23580       |    True   |
| Campbell, Stuart | scampbell | scampbell@bnl.gov |     PS     |       25862       |    True   |
+------------------+-----------+-------------------+------------+-------------------+-----------+

The surname can also be specified with --surnamme:

❯ n2sn_search_user --surname ravel
+--------------+-----------+----------------+------------+-------------------+-----------+
| Name         | ITD Login | E-Mail         | Department | Life/Guest Number | Can Login |
+--------------+-----------+----------------+------------+-------------------+-----------+
| Ravel, Bruce | bravel    | bravel@bnl.gov |     LT     |       R5411       |   False   |
+--------------+-----------+----------------+------------+-------------------+-----------+

Wildcards are also possible, however these need to be added in quotes at the shell:

❯ n2sn_search_user --surname 'farns*'
+---------------------+-----------+-------------+------------+-------------------+-----------+
| Name                | ITD Login | E-Mail      | Department | Life/Guest Number | Can Login |
+---------------------+-----------+-------------+------------+-------------------+-----------+
| Farnsworth, Richard | rif       | rif@bnl.gov |     PS     |       25764       |   False   |
+---------------------+-----------+-------------+------------+-------------------+-----------+

In addition to these search mode, the search can be limited by department by adding the options:

• --staff Limit to NSLS-II staff (Department code PS)

• --users Limit to NSLS-II users (Department code LT)

• --cfn Limit to CFN Staff (Department code NC)

Listing users who can login to instruments

In order to list the users who are currently able to login to a beamline, the command n2sn_list_users can be used.

❯ n2sn_list_users

Current users enabled for beamline CSX

+-----------------+-----------+------------------+------------+-------------------+-----------+
| Name            | ITD Login | E-Mail           | Department | Life/Guest Number | Can Login |
+-----------------+-----------+------------------+------------+-------------------+-----------+
| Wilkins, Stuart | swilkins  | swilkins@bnl.gov |     PS     |       23580       |    True   |
+-----------------+-----------+------------------+------------+-------------------+-----------+

At the instrument (beamline) the instrument name default should be set. This can be overridden by adding the --instrument option:

❯ n2sn_list_users -i fxi

Current users enabled for instrument FXI

+-----------------+----------+------------------+------------+-------------------+-----------+
| Name            | Login    | E-Mail           | Department | Life/Guest Number | Can Login |

+-----------------+----------+------------------+------------+-------------------+-----------+

Listing instrument staff

Similar to listing users, instrument staff can be listed using the n2sn_list_staff. The default instrument can also be overriden using the -i argument as in the case of n2sn_list_users:

❯ n2sn_list_staff -i fxi

Current instrument staff for instrument FXI

+------------------+-----------+-------------------+------------+-------------------+-----------+
