I've tried several times to reproduce this issue on two Debian Edu  
versions (two separate instances of version 12.8 and version 12.9).

1. All new made users of both types (students and teachers) were  
created successfully

2. Passwords changed successfully
(and could not set a password with extra-Unicode chars due to password  
symbol-set restrictions)

3. I see the same warnings:
Deprecated: substr(): Passing null to parameter #1 ($string) of type  
string is deprecated in  
/usr/share/gosa/plugins/admin/users/class_userManagement.inc on line 352
Deprecated: Function utf8 decode() is deprecated in  
/usr/share/gosa/include/password-methods/class_password-methods.inc on  
line 391
.. but it does not prevent to set and use new passwords.

> 4. try to login using the password
4. successfully logged:
  - on ws01 (added as a workstation to domain "intern")
additional info with required steps for workstation:
https://wiki.debian.org/DebianEdu/Documentation/Bookworm/GettingStarted#Machine_Management_with_GOsa.2BALI-
```
Workstations with disks (including separate LTSP servers) have to be  
added with GOsa². Behind the scenes, both a machine specific Kerberos  
Principal (sort of account) and a related keytab file (containing a  
key used as password) are generated; the keytab file needs to be  
present on the workstation to be able to mount users' home  
directories. Once the added system has been rebooted, log into it as  
root and run /usr/share/debian-edu-config/tools/copy-host-keytab.
```
  - on diskless think-client
  - on tjener (server)
  - on GOSa (internal website)

5. could you please add more details regarding the issue?
Where persists the problem with logging in (web,tjener,diskless  
client,workstation)?
Could you add log messages with this error (root at tjener# journalctl -e)?
Have you probably set a password with some special characters?
