Summary: multi-valued attributes returned from an ldap lookup
parsing is hard
Product: Exim
Version: 4.67
Platform: x86
OS/Version: Linux
Status: NEW
Severity: bug
Priority: low
Component: Lookups
AssignedTo: nigel@exim.org
ReportedBy: jgh146exb@wizmail.org

ldap lookup patch for multi-valued attributes
The ldap lookup code returns a multi-valued attribute as a list separated by
comma, space. This presents a problem when a value might contain that
sequence.
The docs only say "separated by commas".
The problem is likely to exist on all platforms and OS'.
A suggested fix:
1) Double any comma in an attribute value as a means of quoting it.
Issue: this is an incompatible change at least for single-value
attributes, and for when users are already successfully parsing
multi-value.
2) Change the the list separator to be only the comma.
Issue: this is an incompatible change which will affect existing
parsing code (unless using exim's builtin list parsing).
Assumption: the space is mainly for human-readability.
