hi
I have a nextcloud server connected to active directory. Upload speed for ldap users is around 40 mbps while local users have upload speed of more than 100 mbps from the same workstation. Also when uploading large files, ldap users get disconnected and logout with error (included in this post) after around 5 to 6 minutes.
I have reinstalled the system on a new server (old server was on centos 7 and the new one has centos 9) and the problem exists.
please help
The Basics
- Nextcloud Server version (e.g., 29.x.x):
23.0.12
- Operating system and version (e.g., Ubuntu 24.04):
centos 9
- Web server and version (e.g, Apache 2.4.25):
apache 2.4.62
- Reverse proxy and version _(e.g. nginx 1.27.2)
replace me
- PHP version (e.g, 8.3):
8.0
- Is this the first time you’ve seen this error? (Yes / No):
Yes
- When did this problem seem to first start?
- ``
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
Bare Metal/
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
slow upload speed for ldap users
frequent disconnect (logout) when uploading large files for ldap users
Steps to replicate it (hint: details matter!):

Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
