PAM setquota module

This module sets disk quota when a session begins.

This makes quotas usable with central user databases, such as LDAP.

Usage

pam_setquota applies a specific disk quota to users (with uid >= 1000).

Limits can be passed to pam_setquota.so through the PAM configuration. They take the form type=soft,hard, where:

• type is either blocks or inodes:
  • blocks limits the space usage, expressed in bytes;
  • inodes limits the number of filesystem objects (file, folder, ...)
• soft (resp. hard) is the decimal value of the soft limit.

See quotactl(2) for further information.

Missing features (TODOs)

Compared to the original C version, we miss the following functionality:

• configurable uid ranges;
• configurable directory;
• override flag.

Example

session    required     /lib/security/pam_setquota.so blocks=19000,20000 inodes=3000,4000
