Question

How can I match a user's wiki name to his login name in a case-insensitive way?

For example, given this line in the TWikiUsers page:

• AndrewBanks - abanks - 1 Jun 2006

how can I get TWiki to say the user is AndrewBanks whether he signs in as abanks, Abanks, or ABanks?

Because I use the LdapContrib plugin and because LDAP is case-insensitive, he is allowed in however he types his username. But the topics that he edits are not signed AndrewBanks unless he uses all lower case, as I have in the TWikiUsers topic. If he types ABanks then it calls him Main.ABanks.

Please do not advise me to use the LdapUserMapping module. It is too slow without ModPerl, and TWiki is too flakey with ModPerl

 }

Because Andrew has found a solution for his own installation and the feature request is in consideration for TWiki 4.2, I'm closing this as a support question, and move most parts of the discussion to Codev.CaseInsensitiveUserMapping.

This has been added to the latest LdapContrib release.

I tested it with the new LdapContrib? in TWiki 4.1.2. On my system there is the problem that now the login name must be case-sensitive. I need a case-insensitive way to login. It would be greatful, if anybody could help me in this point?
