+??nssdb What happened to the Berkeley DB libraries? Can I still use db
+ in /etc/nsswitch.conf?
+
+{AJ} Due to too many incompatible changes in disk layout and API of Berkeley
+DB and a too tight coupling of libc and libdb, the db library has been
+removed completely from glibc 2.2. The only place that really used the
+Berkeley DB was the NSS db module.
+
+The NSS db module has been rewritten to support a number of different
+versions of Berkeley DB for the NSS db module. Currently the releases 2.x
+and 3.x of Berkeley DB are supported. The older db 1.85 library is not
+supported. You can use the version from glibc 2.1.x or download a version
+from Sleepycat Software (http://www.sleepycat.com). The library has to be
+compiled as shared library and installed in the system lib directory
+(normally /lib). The library needs to have a special soname to be found by
+the NSS module.
+
+If public structures change in a new Berkeley db release, this needs to be
+reflected in glibc.
+
+Currently the code searches for libraries with a soname of "libdb.so.3"
+(that's the name from db 2.4.14 which comes with glibc 2.1.x) and
+"libdb-3.0.so" (the name used by db 3.0.55 as default).

-
-{AJ} The GNU C library 2.1 uses db2 instead of db1 which was used in version
-2.0. The internal formats of the actual db files are different. To convert
-the db files from db1 format to db2 format, you can use the programs
-`db_dump185' and `db_load'. Alternativly programs can be linked with db1
-using `-ldb1' instead of linking with db2 which uses `-ldb'. Linking with
-db1 might be preferable if older programs need to access the db file.
-
-db2 supports the old db1 programming interface and also a new programming
-interface. For compilation with the old API, <db_185.h> has to be included
