ud.conf - ud configuration file
The ud configuration file is used to set system-wide defaults to be applied when running
ud. Note that each user may specify an optional configuration file, .udrc, in his/her
home directory which will be used instead of the system-wide configuration file.
The different configuration options are:
Used to specify the name of an LDAP server to which ud should connect. There
may be only one entry per config file. The server's name can be specified as a
domain-style name or an IP address.
Used to specify the search base to use when performing search operations. The
base may be changed by those using ud by using the cb command. There may be
only one entry per config file. The base must be specified as a Distinguished
Name in LDAP format.
Used to specify the base used when creating groups. The base may be changed by
those using ud by using the changegroup command. There may be only one entry
per config file. The base must be specified as a Distinguished Name in LDAP
Used to specify a search algorithm to use when performing searches. More than
one algorithm may be specified, and each is tried in turn until a suitable
response is found.
Each algorithm specifies a filter that should be used when performing a find
operation. Filters contain LDAP-style attribute types (e.g., uid, cn, postalAd-
dress) and operators to test for equality or approximate equality. Prefix oper-
ators may also be used to specify AND, OR and NOT operations (see ldap(3) for
more details on the filter format). Algorithms use a compile-time constant as a
separator to use when parsing the input the user has provided. This parsed
input can then be referenced similarly to an awk program using symbols like $1,
$2, and $0 for the entire batch of input.
For example, the algoritm cn=$0 causes ud to perform a lookup on the entire
string the user has typed, searching for anything where the commonName exactly
matches the whole thing.
Another example, sn~=$NF causes ud to do a search where the last element the
user has typed (NF = number of fields and is a special "number" that can be used
in awk as well as ud) searching for any matches that approximately match Sur-
Search algorithms also support a special feature which allows one to specify the
exact number of fields that must be present in order for the algorithm to be
applied. This number must be specified between square brackets.
For example,  uid=$1 causes this algorithm to be applied when the number of
fields is exactly equal to one. If there is exactly one field, the token is
looked up as a UID.
