Points to Ponder about HTACCESS

1) Using a file including user code information for authorizing web pages:

If an ".htaccess" file is created to invoke the information of authorized usercodes existing in another file, full path address of that file must be specified.

For example:
The address of the file including the information of usercodes (in this example, "passwd" file in "/home999/wwwqqqq/etc/" directory) must be specified as;

AuthName title_to_be_displayed_on_logon_dialog_window
AuthType Basic
AuthUserFile /homewww/wwwqqqq/etc/passwd
require user usercode

instead of

AuthName title_to_be_displayed_on_logon_dialog_window
AuthType Basic
AuthUserFile /home999/wwwqqqq/etc/passwd
require user usercode

in ".htaccess" file. (To remain unaffected by the change in central server, "homewww" should be used instead of "home999" in the file address).

2) Using the passwords defined on central servers for authorizing specific usercodes:

If the passwords defined on central servers will be used for authorizing specific usercodes, ".htaccess" file should be created as below:

AuthName title_to_be_displayed_on_logon_dialog_window
AuthType Basic
AuthBasicProvider ldap
AuthzLDAPAuthoritative Off
AuthLDAPURL "ldap://auth.metu.edu.tr/ou=People,dc=metu,dc=edu,dc=tr"
require user usercode1
require user usercode2
require user usercode3

NOTE: Any number of usercodes defined on central servers can be added as in "require user usercode#" rows.

Using the passwords defined on central servers for authorizing specific usercode categories:

If the passwords defined on central servers will be used for authorizing specific usercode categories (e.g., research assistants (minor category) in ABC department (major category)), ".htaccess" file should be created as below:

AuthName title_to_be_displayed_on_logon_dialog_window
AuthType Basic
AuthBasicProvider ldap
AuthzLDAPAuthoritative Off
AuthLDAPURL ldap://auth.metu.edu.tr/ou=People,dc=metu,dc=edu,dc=tr?uid??(&(major=ABC)(minor=rsc))

In order to see the major and minor definitions of usercodes, "id usercode" command can be used. This command can be used while being connected to central servers.

For example;

As the command "id abcde " is used to learn the major and minor categories of usercode "abcde ", assume that following output has been displayed:

uid=1049(abcde) gid=10044(asd_rsc)

This information reveals that, "abcde " usercode belongs to a "research assistant" working in a department/unit having the ECS (Electronic Communication System) usercode of "asd".

Some of the minor categories are listed below:

	bs	Undergraduate student
	rsc	Research assistant
	ms	Graduate student
	phd	Doctoral student
	aca	Academic personnel
	adm	Administrative personnel
	spc	Special student

Major categories of departments/units can be learned from the page "Electronic Communication System Usercodes List" including the information of usercodes defined for departments/units.

To have detailed information about authorizing usercode categories using LDAP application, please visit the page General Information about LDAP".
