This commit replaces the LDAP client TLS config and
adds a custom list of TLS cipher suites which support
RSA key exchange (RSA kex).
Some LDAP server connections experience a significant slowdown
when these cipher suites are not available. The Go TLS stack
disables them by default. (Can be enabled via GODEBUG=tlsrsakex=1).
fixes https://github.com/minio/minio/issues/20214
With a custom list of TLS ciphers, Go can pick the TLS RSA key-exchange
cipher. Ref:
```
if c.CipherSuites != nil {
return c.CipherSuites
}
if tlsrsakex.Value() == "1" {
return defaultCipherSuitesWithRSAKex
}
```

In regular listing, this commit will avoid showing an object when its
latest version has a pending or failed deletion. In replicated setup.
It will also prevent showing older versions in the same case.
without atomic load() it is possible that for
a slow receiver we would get into a hot-loop, when
logCh is full and there are many incoming callers.
to avoid this as a workaround enable BATCH_SIZE
greater than 100 to ensure that your slow receiver
receives data in bulk to avoid being throttled in
some manner.
this PR however fixes the unprotected access to
the current workers value.
Add the inlined data as base64 encoded field and try to add a string version if feasible.
Example:
```
λ xl-meta -data xl.meta
{
"8e03504e-1123-4957-b272-7bc53eda0d55": {
"bitrot_valid": true,
"bytes": 58,
"data_base64": "Z29sYW5nLm9yZy94L3N5cyB2MC4xNS4wIC8=",
"data_string": "golang.org/x/sys v0.15.0 /"
}
```
The string will have quotes, newlines escaped to produce valid JSON.
If content isn't valid utf8 or the encoding otherwise fails, only the base64 data will be added.
`-export` can still be used separately to extract the data as files (including bitrot).
Add partial shard reconstruction
* Add partial shard reconstruction
* Fix padding causing the last shard to be rejected
* Add md5 checks on single parts
* Move md5 verified to `verified/filename.ext`
* Move complete (without md5) to `complete/filename.ext.partno`
It's not pretty, but at least now the md5 gives some confidence it works correctly.
precondition check was being honored before, validating
if anonymous access is allowed on the metadata of an
object, leading to metadata disclosure of the following
headers.

although the information presented is minimal in nature,
and of opaque nature. It still simply discloses that an
object by a specific name exists or not without even having
enough permissions.
This change uses the updated ldap library in minio/pkg (bumped
up to v3). A new config parameter is added for LDAP configuration to
specify extra user attributes to load from the LDAP server and to store
them as additional claims for the user.
A test is added in sts_handlers.go that shows how to access the LDAP
attributes as a claim.
This is in preparation for adding SSH pubkey authentication to MinIO's SFTP
integration.
