ldap.DECODING_ERROR when adding LDAP-container

I get a ldap.DECODING_ERROR when adding LDAP-container usign this:

udm container/cn create \
--position "cn=custom attributes,cn=univention,$ldap_base" \
--set name="Nextcloud"

The Error:

Traceback (most recent call last):

ldap.DECODING_ERROR

creating the object with the correct domain isntead of the variable “$ldap_base” works.

The ldap.DECODING_ERROR is typical if the $ldap_base variable is empty. UDM then tries to create an object at cn=Nextcloud,cn=custom attributes,cn=univention, - which is not a valid DN.

To make this work, you need to first set ldap_base to an actual value. The most convenient way to do this:

eval "$(ucr shell ldap/base)"

This will add $ldap_base to your shell variables with the value of the UCR variable ldap/base. You can check with:

echo $ldap_base

You can even load all UCR variables as shell variables by simply executing:

eval "$(ucr shell)"
# happy shell scripting:
printf "Your DNS Forwarder is: $dns_forwarder1 \nYour DNS Nameserver is: $nameserver1 \nYour LDAP server is: $ldap_server_name \nUsed repository server: $repository_online_server \nAre updates available? $update_available \n"
