Multi value Attribute by reading customer information from LDAP

[allo9615]

I read the customer Information from our LDAP. Some of the attributes are multivalue, they can have many values at the same time e. g. many telephone numbers or many roles at the organisation.
At the moment OTRS read only the first value but I need all of them and show them in the customer information box.
Could please somebody show me how to read those multivalue attributes from LDAP and show the in OTRS.
Thank you in advance
