            Bug ID: 2646
           Summary: taint error in ldap query parameter
           Product: Exim
           Version: 4.94
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Lookups
          Assignee: unallocated@???
          Reporter: heiko@???

Exim fails with taint error if a server parameter is specified.

Reproduce:

Argument "-oMai" is used in the following example only to fill
$authenticated_id with an tained value.

$ exim -oMai example -be '${lookup ldap {ldap:///attr=$authenticated_id}}'
--> works as expected

but:

$ exim -oMai example -be '${lookup ldap {servers="localhost"
ldap:///attr=$authenticated_id}}'

That's not correct. Nothing in the added parameter (servers="localhost") should
cause a taint mismatch.
