**Problem:** 
Some AD users can't log in, they get the error:
`Authentification failed: password is incorrect or there is no user with such name`

Clickhouse version 22.3.2.1

**There is an error in Clickhouse logs:**
`<Error> Access(user directories): from: 10.11.12.13, user: AD_USERNAME: Authentification failed: Code: 532. DB::Exception: Size limit exceeded. (LDAP_ERROR)`

This error occurs for AD users who have many groups in the **memberOf** LDAP container.

**I checked the number of groups for 4 accounts:**

AD_USERNAME_1 - 107 groups - ERROR Authentification failed
AD_USERNAME_2 - 120 groups - ERROR Authentification failed
AD_USERNAME_3 - 54   groups - OK
AD_USERNAME_4 - 38   groups - OK

**I checked the search groups through the Ldapsearch program:**

Ldapsearch gave all 107 groups for the account without errors:
`ldapsearch -H "ldaps://hostname:636" -D 'CN=AD_USERNAME_1,OU=Users,DC=company,DC=corp.DC=net' -b 'DC=company,DC=corp.DC=net' '(&(objectClass=group)(member=CN=AD_USERNAME_1,OU=Groups,DC=company,DC=corp.DC=net))'`

**Probable cause of the error:** 
Clickhouse receives a list of groups which mapping from AD and cannot process a large string/array.

    parseLDAPSearchParams(params, config, prefix);
    const bool has_prefix = config.has(prefix + ".prefix");
    if (has_prefix)
        params.prefix = config.getString(prefix + ".prefix");
