Enable LDAP User SSH to Synology NAS
Securing the connection to your NAS
Users created with Synology’s LDAP Server have their login shell set to /sbin/nologin. Add the following to the end of /usr/syno/etc/nslcd.conf if you want to enable SSH logins to your NAS for your LDAP users:
map passwd loginShell "/bin/sh"
Then run the following command:
$ synoservice --restart nslcd
Your LDAP users should now be able to SSH into the Synology NAS, in this case using a password-less SSH key:
$ ssh ldaptest@synology
ldaptest@synology:~$ exit
logout
Connection to synology closed.
