Maybe you will find your answer in this guide

Also I can recommend you if you use Connector type of directory try to synchronise directory. It should help

I can't find what is external_id in the spec, but as I know, it's the field by which you tell Crowd, that your user_A (from Crowd) is linked to one of your users from directory. 
Description from the Crowd: "The attribute field to use for tracking user identity across user renames". So for example, if you rename your user, Crowd will find your user by this field.
And better to use unique identifier, for example in LDAP it's uid field, and for AD - entryUUID field

Hi @Peruma Chinnasamy  and welcome to the community. 

Can you please describe your problem more clearly? How I can achieve your state? What version of Crowd do you use? And what exactly going wrong with your external id?

[Peruma Chinnasamy]

Hi Roman,

I was upgraded crowd v 3.7 into 4.4.0 version in non prod crowd application. In 4.4.0 version few old user  facing login issue. Those who are having the external id >32 characters. So we are planning to regenerate the external id those who are having external id >32 characters  to avoid login issue. 

Thanks and Regards

Which type of directory do you have?

[Peruma Chinnasamy]

We have LL AD and LL EXT directory.

[Roman Kovalov]

When you adding a directory, you can select one of it type from this fields:

Also you can check it type from DB: cwd_directory table, directory_type field

[Peruma Chinnasamy]

The directory type is "Delegated Authentication"

[Roman Kovalov]

Ok, great! So that should be easier:) 

You can delete user_A from Crowd (better to do it from UI). It will not affect your user from directory.
And after you login to application with user_A it should appear in Crowd and have correct external_id.

Hi Roman,

Thank you for your valuable input.

I would like to mention few thing here.

More than 10 thousand user will face this login issue after prod crowd 4.4.0 version.

So I need fix before upgrading prod crowd. Any other fix is there doing bulk external Id regeneration.

Thanks and Regards

Ok, so one of possible solutions is to re-add directory.
Or try to use connector type of directory, which will help to resolve issues like this with synchronization feature (unfortunately there is no synchronization in Delegated).

Hope that will resolve the issue.
Roman.
