Detailed Description

Currently, the Fedora provided BerkeleyDB versions is 5.x, which has been unmaintained upstream for several years. BerkeleyDB v6.x is license incompatible, so moving to that version is not an option.

The proposal is to switch to GDBM, which has upstream support and whose license is compatible with Fedora.

Benefit to Fedora

• This changes uses an upstream maintained version, with new features and bug fixing. pam_userdb controls user authentication, and a bug in the database could lead to a security vulnerability.
• This change uses a database that is Fedora license compatible.
