• Message number: 078

• Message text: Illegal character in the registration data of the LDAP Connector

What causes this issue?

The LDAP Connector "&V1&" is to be started.
When starting the LDAP Connector, the system reads the values for
gateway host, gateway service, and program ID entered in the RFC c
onnection with the same name.
These values are:
Gateway host: &V2&
Gateway service: &V3&
Program ID: &V4&
One of these values, or the name of the LDAP Connector itself, contains
an invalid character, which can prevent the starting of the LDAP
Connector with operating system resources.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
