what should happen if you have {"alpha":{"a","b"}, "ALPHA": {"c", "d"}} and you search for "Alpha"?

is that possible? isn't the attribute name case insensitive?

Shall we at least add a test case with attribute names differing only in case and document via the tests how we'd handle it? That way at least it's more obvious.

I'd like to see the case sensitivity to be toggled by a package variable ( |

I still think it's a mistake to compress the value space by default. Explicitly case-insensitive lookup functions seem clearer to me. Would also need to define the behavior for that (does it prefer an exact matching name over a case insensitive name match that comes first in order? Does it aggregate values specified for names that differ only by case?) |

these are the case insensitive counter parts, e.g. GetAttributeValue <=> GetEqualFoldAttributeValue using strings.EqualFold to compare the attrribute names fixes go-ldap#109 go-ldap#129

@johnweldon @liggitt can we merge this? |
LDAP itself doesn't match attributes case-sensitively, so a query for
(fOO=bar)
will return all the entries having `foo: bar`, regardless of how the
attribute name is defined in the schema.
However, the result entries we get will have the case according to what
the server returned. So, assuming the schema calls it `foo`, this is
what we're given.
Now, for certain attributes that are user-configurable -- NameAttr for
example -- this can cause trouble: the query returns the right results,
but the LDAP connector can't make sense of it as it's looking for an
attribute called `fOO`.
The real life case underlying this conundrum is Active Directory's
sAMAccountName.
Note that this is a bit of a workaround. Ideally, we'd use
`(*ldap.Entry).GetAttributes(string) []string` to access the attributes;
but until the case sensitivity issue is fixed there[1], changing the way
we read the results doesn't help us.

I'd like to have this fix as well. Any ETA for merging it? |

@liggitt 🏓 Any news regarding this? 😃 |

This is the same way an LDAP server compares during a search request.
Fixes #109
