[exim] Problem to Authenticate against two LDAP's

Hello all,

I am using exim4 version 4.89 as smtp-auth server. The exim should
authenticate against two LDAP servers.

I can optionally authenticate against one or the other.

To be able to authenticate against both, I replaced the "if" with an "if
or" and wrote both conditions in parentheses one after the other.

The problem, however, is that there is always an error message:

Unable to authenticate at present (set_id=xxxxx): missing } at end of
condition inside "or" group

The whole call looks like this:

   server_condition = \
   ${if or \
     { \
       { \
         ldapauth \
           {user=${if eq {}{${lookup ldapdn 
{ldap://ldap1.abc.net/LDAP_BASE??sub?(|(uid=${quote_ldap:$2})(mail=${quote_ldap:$2})(mailAlias=${quote_ldap:$2})(mailAlternateAddress=${quote_ldap:$2}))}}} 
\
           {uid=dummyuser} \
           {${quote:${lookup ldapdn 
{ldap://ldap1.abc.net/LDAP_BASE??sub?(|(uid=$2)(mail=$2)(mailAlias=$2)(mailAlternateAddress=$2))}}}}} 
\
           pass=${quote:$3} \
           ldap://ldap1.abc.net/}{yes}{no}}\
       } \
       { \
         ldapauth \
           {user=${if eq {}{${lookup ldapdn 
{ldap://ldap2.abc.net/ou=Internet,ou=abc-intern,o=net?dn?sub?(&(|(uid=${quote_ldap:$2})(mail=${quote_ldap:$2})(mailAlternateAddress=${quote_ldap:$2}))(!(accountClosed=1)))}}} 
\
           {uid=dummyuser} \
           {${quote:${lookup ldapdn 
{ldap://ldap2.abc.net/ou=Internet,ou=abc-intern,o=net?dn?sub?(&(|(uid=${quote_ldap:$2})(mail=${quote_ldap:$2})(mailAlternateAddress=${quote_ldap:$2}))(!(accountClosed=1)))}}}}} 
\
           pass=${quote:$3} \
           ldap://ldap2.abc.net/}{yes}{no}}\
       } \
     } \
   }

Does anyone have any idea how I could solve this?
