Next generation libnss Berkeley DB backend

libnss_dbng - Next-generation Berkeley DB libnss backend

This library replaces the older libnss_db library. Apart from being a fresh, legacy-free & maintained codebase, it aims to make the following improvements:

• Use more modern versions of Berkeley DB.
• Make use of secondary indexes for fast lookups (ie lookup by UID or name in the case of passwd).
• Have good test coverage via automated unit tests.
• Provide a management library (libdbng) and sample frontend (dbngctl) to allow applications to safely manage the databases, as well as the core nss functions themselves.

Components

In addition to the libnss functions, the following components are provided to manage the service databases:

• libdbng - Object-oriented library to manage service databases (and secondary indexes transparently).
• dbngctl - Control program to allow administrators to manage service databases from the command line. Makes use of libdbng.
• DBNG::Service - OO PERL extension which links against libdbng.

Building

The library requires Berkeley DB (4.x or 5.x).

Via autotools, use something like:

  $ autoreconf -i
  $ ./configure DEFAULT_BASE="/var/dbng" TEST_BASE="/tmp" && make
  $ make check && sudo make install

Status

Currently the passwd, group and shadow services are implemented.

libnss-dbng's Issues

License

Are you willing to change the License to GPL-2 ?
Using GPL-3 makes it impossible to use this code in cryptographic signed images, GPL-2 would allow this.

support pam-userdb

Hey Mikey

libnss-dbng is a really impressive code.

i am using it together with libpam-userdb ( offical pam module )

and i would like to ask if there is interest for adding support for the pam password database.

This would extend the dbngctl tool ( and libdbng.so.0.0.0) for an additional simple user/passwd database that can be used by libpam-userdb.

So my question is if you would be interested to accept a patch, otherwise i would write a independent binary and leave you code untouched.

greetings
