nisldapmaptest

- test NIS+ and LDAP mapping configuration files

Synopsis

nisldapmaptest [-s | -r | -d] [-l | -t object] [-v] [-i] 
     [-o] [-m conffile] [-x attr=val...] [ col=val]...

Description

Use the nisldapmaptest utility to test NIS+ to LDAP mapping configuration files. See NIS+LDAPmapping(4). The nisldapmaptest utility uses much of the same internal interface as the rpc.nisd(1M) does to read, add, modify, or delete LDAP data, as specified by the column name and value operand pairs. nisldapmaptest does not read or modify any of the rpc.nisd(1M) database files.

See Notes for details on important differences between the ways that nisldapmaptest and rpc.nisd(1M) operate on LDAP data.

Options

The nisldapmaptest utility supports the following options:

-d

Delete data in LDAP.

-i

Ignore failures when obtaining information from the NIS+ server. This enables nisldapmaptest to work to some extent, even if the NIS+ server is unreachable, or if the system is not a NIS+ client. However, NIS+ lookups are still attempted, so there may be NIS+ error messages.

In this mode, nisldapmaptest also tries to guess things such as NIS+ object types and derives table column information from the mapping rules in the configuration files. Avoid using the -i option to add, modify, or delete, until you have determined that the nisldapmaptest's guesses are adequate for your needs.

-l

Parse the configuration file into internal data structures, and then print out the configuration per those structures. Note that the printed data is not in configuration file format.

Either -l or -t must be specified. If both are present, -l is ignored.

-m conffile

Specify the name of the NIS+LDAPmapping(4) configuration file. The default directory is /var/nis , and the default mapping file is NIS+LDAPmapping.

-o

For NIS+ tables, work on the NIS+ object itself, specified by means of the -t option, not on the table entries.

-r

Replace or add data in LDAP.

-s

Search for data in LDAP. This is the default.

-t object

Specify the NIS+ object on which to operate. If the object name is not fully qualified, that is, it does not end in a dot, the value of the nisplusLDAPbaseDomain attribute is appended.

-v

Set the verbose flag. This flag produces extra diagnostic information.

-x attr=val...

Specify mapping attribute and value pairs to override those obtained by means of the configuration file. Although any attributes defined on NIS+LDAPmapping(4) or rpc.nisd(4) can be specified, the ones that control rpc.nisd(1M) operation have no effect on nisldapmaptest.

Operands

The following operands are supported:

col=val...

NIS+ column and value pairs used to specify which entries should be looked up, added, modified, or deleted. For additions and modifications, use col=val to specify the new values.

Examples

Example 1 Searching for a User

Use the following example to search for the user xyzzy in the LDAP container specified for the passwd.org_dir table.

example% nisldapmaptest -t passwd.org_dir name=xyzzy

Example 2 Listing Table Entries

Use the following example to list all entries in the container specified for the services.org_dir table.

example% nisldapmaptest -t services.org_dir

Example 3 Listing an Object

Use the following example to list the services.org_dir object itself, as it is stored in LDAP.

example% nisldapmaptest -o -t services.org_dir

Example 4 Modifying a Table Entry

Use the following example to modify the membership list of the group grp, in the container specified for the group.org_dir table, to be mem1, mem2, and mem3.

example% nisldapmaptest -r -t group.org_dir name=grp \
     members=mem1,mem2,mem3

Example 5 Deleting a Table Entry

Use the following example to delete the host called bad from the container specified for the hosts.org_dir table.

example% nisldapmaptest -d -t hosts.org_dir name=bad

Exit Status

The following exit values are returned:

0

The requested operation was successful.

!= 0

An error occurred.

Notes

There are several differences between the ways that nisldapmaptest and rpc.nisd operate:

1. nisldapmaptest obtains information about NIS+ by means of the NIS+ API calls, while rpc.nisd looks in its internal database. Thus, if the NIS+ server is not available, nisldapmaptest may be unable to determine NIS+ object types or table column information.

2. While nisldapmaptest can add, modify, or delete LDAP data, it does not modify any NIS+ data.

3. When operating on table entries, if nisldapmaptest is unable to obtain the entry from NIS+, it composes LDAP operations using only the supplied col=val operands. Depending on the mapping used, this can result in extra LDAP operations, for example, attempting to obtain a DN for add, modify, or delete.

4. The default value for nisplusLDAPbaseDomain is the system domain name per sysinfo(2) in nisldapmaptest, but the internal notion of the domain it serves in rpc.nisd. While the two usually are the same, this is not necessarily always the case.

5. When more than one NIS+ entry maps to a single LDAP entry, nisldapmaptest may be unable to perform a complete update, unless you make sure that the col=val specification picks up all relevant NIS+ entries. For example, if you have the services.org_dir NIS+ entries:

   cname   name    proto   port
   
   x       x       tcp     12345
   x       y       tcp     12345
   x       z       tcp     12345

   then specifying cname=x will pick up all three entries and create or modify the corresponding LDAP entry to have three CN values: x, y, and z. However, specifying name=x will match just the first NIS+ entry, and create or modify the LDAP entry to have just one CN: x.
