Change sponsored?: ---
Product: Koha

# Description
After enabling the StockRotation system preference, all LDAP users fail to log
in to the OPAC.
This occurs consistently in my environment with the following LDAP
configuration in `koha-conf.xml`:
<useldapserver>1</useldapserver><!-- see C4::Auth_with_ldap for extra configs
you must add if you want to turn this on -->
<ldapserver id="ldapserver" listenref="ldapserver">
<hostname>ldaps://freeipa.example.org:636</hostname>
<user>uid=admin,cn=users,cn=accounts,dc=example,dc=org</user>
<base>cn=users,cn=accounts,dc=example,dc=org</base>
<pass>********</pass>
<auth_by_bind>1</auth_by_bind>
<replicate>1</replicate>
<update>1</update>
<update_password>0</update_password>
<anonymous_bind>0</anonymous_bind>
<principal_name>uid=%s,cn=users,cn=accounts,dc=example,dc=org</principal_name>
<mapping>
<userid is="uid"></userid>
<cardnumber is="uid"></cardnumber>
<email is="mail"></email>
<surname is="sn"></surname>
<firstname is="givenname">-</firstname>
<password is="userPassword"></password>
<address is="address">Default Address</address>
<city is="city">Default City</city>
<categorycode is="1">01</categorycode>
<branchcode is="1">01</branchcode>
</mapping>
</ldapserver>
# Steps to reproduce
1. Enable LDAP authentication in `koha-conf.xml` (see config above). Confirm
LDAP users can log in to OPAC.
2. Enable the StockRotation system preference in Administration → Global system
preferences.
3. Attempt to log in as an LDAP user in OPAC.
# Expected result
LDAP users can still authenticate normally after enabling StockRotation.
# Actual result
LDAP users are unable to log in to OPAC. Local database accounts remain
unaffected.
# Additional notes
- Disabling StockRotation immediately restores LDAP login functionality.
- This was observed in my production environment; I have not tested on a
completely fresh Koha installation due to resource limits.
- No relevant changes observed in `opac-error.log`
