When a user is using an IPv6 address, they can't log in and we are getting the following error:

Maximum length of IPv6 address is 39. I think that ipnr column of your auth_cookie table is incorrect and an installation issue. Please check definition of auth_cookie table with DESC auth_cookie; and SHOW CREATE TABLE auth_cookie\G.

Anyway, this issue is not an AccountManagerPlugin issue neither a Trac issue.

Thanks for the reply, I'm just trying to fix the issue and I wasn't sure where to ask.

What should the tables be?

comment:3 Changed 2 years ago by anonymous

This is what I see:

Field name  Type        Allow nulls?    Key    Default value
cookie      varchar(64)     No          Primary     NULL
name        varchar(64)     No          Primary     NULL
ipnr        varchar(32)     No          Primary     NULL
time        int(11)         Yes         None        NULL

All right, I finally fixed, it was so stupid :)

I just changed the width to 64. Not sure if it needs to be something else.

Replying to anonymous:

What should the tables be?

CREATE TABLE auth_cookie (
    `cookie` mediumtext,
    `name` mediumtext,
    `ipnr` mediumtext,
    `time` int,
    PRIMARY KEY (`cookie`(191),`ipnr`(191),`name`(191))

That's for creating a new table, right?

Is it possible to convert the current table without any data loss?

comment:8 Changed 2 years ago by anonymous

Thanks for all the help, all sorted out

CREATE TABLE `auth_cookie2` (
  `cookie` mediumtext COLLATE utf8_bin NOT NULL,
  `name` mediumtext COLLATE utf8_bin NOT NULL,
  `ipnr` mediumtext COLLATE utf8_bin NOT NULL,
  `time` int(11) DEFAULT NULL,
  PRIMARY KEY (`cookie`(111),`ipnr`(111),`name`(111))
INSERT INTO `auth_cookie2` SELECT * from `auth_cookie`;
DROP TABLE `auth_cookie`;
RENAME TABLE `auth_cookie2` TO `auth_cookie`;
