Unfortunatelly I have n o idea how to fix this... Theoretically the toggle must stay on disabled (LDAP without S) but there must be an option for the TLS upgrade.
Following work-arround works for me.
After configuring the LDAP with the proper credentials via WebGUI, WITHOUT(!) SSL/TLS option issue following commands:
echo "TLS_REQCERT allow" >> /etc/ldap/ldap.conf
echo "ssl start_tls" >> /etc/libnss-ldap.conf
echo "ssl start_tls" >> /etc/pam_ldap.conf
and then restart OpenMediaVault.
Open issues:
- I did not figure out how to insert this parameter over WebGUI. As 3 files must be modified probably is not possible to fix this via GUI with only two input fields
- each time the LDAP parameters are changed via the WebGUI, the above work around is going to be overwritten.
