What is a valid screen name? What are the rules?

[13年前 に jeff perreault によって更新されました。]

Hi, I'm having lots of troubles integrating our LDAP with LifeRay.

Are there rules about what a screen name can be?

I cannot seem to create ( manually or using LDAP ) a new user with a screen name consisting of all numbers. This is a problem, since our usernames in LDAP are 9 digit numbers.

Here is the error that I see:

17:26:10,288 ERROR [PortalLDAPImporter:580] Problem adding user with screen name 100383833 and email address test@########.com
com.liferay.portal.UserScreenNameException

What can I do in order to use our LDAP to authenticate LifeRay?

Which version of Liferay Portal are you using. 5.1 CE and 5.2 CE does not allow all numeric screen names because it can potentially cause conflicts in the URL. in 6.0 CE, however, we were able to figure out a solution around this limitation so you should be able to use all numeric screen names in 6.0 CE.

Hi we are evaluating LifeRay Portal v 5.2 EE sp4

It's a show stopper if we can't use LDAP to authenticate. We have dozens of users and our policy is to only have a single login for all of our systems.

Can the ScreenName have spaces? Does it appear in a URL?

What do other LDAP users use as a screen name?

If you're using 5.2 EE SP4 (or 6.0), you can set

users.screen.name.allow.numeric=true

to use numeric screen names. Please note that not all numeric values are allowed as screen names. Numbers used by communities and organizations cannot be used as screen names. More technically, numbers used as a groupId in the Group_ table cannot be used as a screen name.

Can the ScreenName have spaces? Does it appear in a URL?

No. Yes.

Following are some of the validations that i know

Cannot be "postfix" or "cyrus"
cannot be emailaddress
cannot have underscore or forward slash
cannot be null
if screenname is number it cannot be same as userid
cannot be annonymous names of application servers like (anonymous-guest,guest,ANONYMOUS,<anonymous>)
If you have reserved some screennames in portal-ext.properties specified in this property admin.reserved.screen.names then you cant use them.

These are some of the validations that i know of.

Can screen name have a space?

Does the screen name have to be unique?

I'm looking through our LDAP record, and the only unique things we have are:
email
userid - a 9 digit number
uid ( which I do not want to expose )
display name ( which has spaces and is not necessarily unique )

[13年前 に Sandeep Nair によって更新されました。]

As Samuel said screenname cannot have space. Yes screenname has to be unique coz afik screenname is used in making friendly url of user's pvt and public page. Display name liferay takes it by default combination of users first and last name which is used in greeting like Welcome Firstname LastName.

If nothing from ldap maps to liferays screenname you can set following property in portal-ext.properties to true users.screen.name.always.autogenerate=true

This will autogenerate screenname.

Sandeep,
Do you know if this property:

users.screen.name.always.autogenerate=true

still works in version 6.0?

I tried it and I cannot get it to autogenerate screen names.
Also, are you supposed to just leave the screen name mapping field empty?
The LDAP importer complains that screen names can't be null.

[13年前 に Sandeep Nair によって更新されました。]

It says so in portal.properties. I havent tried it.

#
# Set this to true to always autogenerate user screen names even if the user
# gives a specific user screen name. If this is set to true, the LDAP
# importer will fetch users by their email address even if the property
# "company.security.auth.type" is set to screenName.
#
users.screen.name.always.autogenerate=true


Try with fresh instance of tomcat or check for the newly created users after the property is set to true.

Regards,
Sandeep

validation fro screename ==> ScreenNameValidator.java
com.liferay.portal.security.auth

For making changes in user creation as per your post you want to use email-id which is the only unique field try changing UserLocalServiceImpl

Not sure if you ever got around your bug, but for future generations...Screen names can't start with a numeric either. So 1004bob is not a valid option, however bob1004 is perfectly ok.
