The issue you are facing:
For all my ~200 Users that sign in with LDAP, I am facing quota display problems. A quota of 1TB is displayed, while a quota of 500MB is enforced.
- my default quota as per user settings is 500MB:
- I have checked and validated in the database that the quota setting for all my users is set to “default”:
SELECT * FROM preferences where preferences.appid = 'files' and preferences.configkey = 'quota'; - A quota of 500MB is enforced - filling an account with 490 MB and then uploading a 10MB file leads to “insufficient space” errors.
- The visual bar in the files app is based on a 500MB quota. It turns red and almost full when 490MB are in the account.
- This issue does not appear for local users, only for LDAP users.
- In my LDAP sync settings, the fields for “Default Quota” and “Quota Field” are empty.
A few months ago I was syncing this from LDAP, and I may have had a default of 1TB set here (so that’s where the number may come from).
Is this the first time you’ve seen this error? (Y/N): N
It’s been like this for months and multiple nextcloud versions. Users have used multiple browsers, computers, Nextcloud has been restarted and upgraded many times. I will not believe that this is a caching issue 
Does anyone have an idea how to further troubleshoot this?
I can’t find any “cached” quota in the LDAP modules’ config:
mysql> SELECT DISTINCT preferences.configkey FROM preferences where preferences.appid = 'user_ldap';
+---------------------------+
| configkey |
+---------------------------+
| cached-group-memberships- |
| displayName |
| firstLoginAccomplished |
| foundDeleted |
| homePath |
| isDeleted |
| lastAvatarChecksum |
| lastProfileChecksum |
| uid |
+---------------------------+
LDAP Quota in the DB is empty too.
mysql> SELECT * FROM appconfig where appid = 'user_ldap' and configkey = 'ldap_quota_def';
+-----------+----------------+-------------+------+------+
| appid | configkey | configvalue | type | lazy |
+-----------+----------------+-------------+------+------+
| user_ldap | ldap_quota_def | | 2 | 0 |
+-----------+----------------+-------------+------+------+
Thanks for any hint!
