Hello,

we are using JTS/RTC based on Websphere.
The system is LDAP enabled.

Is there any known limitation regarding the length of the user login?

I know 32 characters from ClearQuest.

greetings georg.

Hi Georg,
I know that when you register for jazz.net, your userid must be between 3 and 24 characters.  I'm unsure if RTC has looser restrictions or not.

Hello Georg,

trying to create a new user with a very long ID I got:
Validation errors for item: type = ContributorRecord, itemId = [UUID _QQUzdgTSEeO60uhe7P59lg] Value of attribute "userIds.userId" is 300 bytes, which is greater than the allowed encoded length of 250 bytes.

So I guess 250 bytes is the limit.

Best Regards
Francesco

I write as a co-worker of Georg.

An user weren't able to logon at JTS meanwhile RTC worked. JTS uses Websphere version 7.0.0.19 and RTC uses version 8.0.0.4.

At first we supposed the uid length but the problem was the special character "ยง". In Websphere version 7.0.0.19 it wasn't accepted since version 8.0.0.4 did so.

we are using the UserPrincipalName of the LDAP / Active Directory integration.

In AD this is similar to the e-mail address.

Within our forest (the same as you are using) we have not found any user where the UPN was to o long to be used as userid.
