pam_setquota is a PAM module to set or modify a disk quota at session start
This makes quotas usable with central user databases, such as MySQL or LDAP.
The device file or mountpoint the policy applies to. Defaults to the filesystem containing the users home directory.
Overwrite an existing quota. Note: Enabling this will remove the ability for the admin to manually configure different quotas for users for a filesystem with edquota(8). (Defaults to 0)
Enable debugging. A value of 1 outputs the old and new quota on a device. A value of 2 also prints out the matched and found filesystems should fs be unset. (Defaults to 0)
Describe the start of the UID range the policy is applied to. (Defaults to UID_MIN from login.defs or the uidmin value defined at compile-time if UID_MIN is undefined.)
Describe the end of the UID range the policy is applied to. Setting enduid=0 results in an open-ended UID range (i.e. all uids greater than startuid are included). (Defaults to 0)
Soft limit for disk quota blocks, as defined by quotactl(2). Note: bsoftlimit and bhardlimit must be set at the same time!
Hard limit for disk quota blocks, as defined by quotactl(2). Note: bsoftlimit and bhardlimit must be set at the same time!
Soft limit for inodes, as defined by quotactl(2). Note: isoftlimit and ihardlimit must be set at the same time!
Hard limit for inodes, as defined by quotactl(2). Note: isoftlimit and ihardlimit must be set at the same time!
Module Types Provided
Only the session module type is provided.
The quota was set successfully.
No action was taken because either the UID of the user was outside of the specified range, a quota already existed and overwrite=1 was not configured or no limits were configured at all.
The user was not found.
/proc/mounts could not be opened.
The filesystem or device specified was not found.
The limits for the user could not be retrieved. See syslog for more information.
The limits for the user could not be set. See syslog for more information.
Either isoftlimit/ihardlimit or bsoftlimit/bhardlimit were not set at the same time.
A single invocation of `pam_setquota` applies a specific policy to a UID range. Applying different policies to specific UID ranges is done by invoking pam_setquota more than once. The last matching entry defines the resulting quota.
