d9898ee8 | 82 | Depending on the configuration of the Courier authentication library, |
83 | accounts may have individual options associated with them. | |
84 | If the authentication library configuration does not implement account | |
b0322a85 | 85 | options, the option string will be a <code class="literal">NULL</code> value. |
d9898ee8 | 86 | Otherwise it will be a comma-separated list of |
b0322a85 | 87 | <span class="quote">“<span class="quote"><em class="replaceable"><code>option</code></em>=<em class="replaceable"><code>value</code></em></span>”</span> |
d9898ee8 | 88 | settings.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> |
b0322a85 CE |
89 | The application is responsible for actually implementing the |
90 | options. | |
91 | For example, | |
92 | sn authentication request for service <span class="quote">“<span class="quote">imap</span>”</span>, for example, | |
93 | will succeed provided that the userid and the password are valid, | |
94 | even if <span class="quote">“<span class="quote">disableimap=1</span>”</span> is set. | |
95 | The application's <code class="function">callback_func</code> should check for this | |
96 | condition, and return a negative return code.</p></div><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> | |
97 | The following list of account options is a combined list of implemented | |
98 | options supported by Courier, Courier-IMAP, and | |
d9898ee8 | 99 | SqWebMail packages. Some of the following information is obviously |
100 | not applicable for a particular package. | |
101 | The inapplicable bits should be obvious.</p></div><p> | |
102 | The following options are recognized by the various Courier | |
b0322a85 | 103 | packages:</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="literal">disableimap=</code><em class="replaceable"><code>n</code></em></span></dt><dd><p> |
d9898ee8 | 104 | If "n" is 1, IMAP access to this account should be disabled.</p></dd><dt><span class="term"><code class="literal">disablepop3=</code><em class="replaceable"><code>n</code></em></span></dt><dd><p> |

107 | If "n" is 1, unencrypted POP3 access to this account should be disabled.</p></dd><dt><span class="term"><code class="literal">disablewebmail=</code><em class="replaceable"><code>n</code></em></span></dt><dd><p> | |
d9898ee8 | 108 | If "n" is 1, webmail access to this account should be disabled.</p></dd><dt><span class="term"><code class="literal">disableshared=</code><em class="replaceable"><code>n</code></em></span></dt><dd><p> |
109 | If "n" is 1, this account should not have access to shared folders or be able | |
110 | to share its own folders with other people.</p></dd><dt><span class="term"><code class="literal">group=</code><em class="replaceable"><code>name</code></em></span></dt><dd><p> | |
b0322a85 CE |
111 | This option is used by Courier-IMAP in calculating access control lists. |
112 | This option places the account as a member of access group | |
d9898ee8 | 113 | <em class="replaceable"><code>name</code></em>. |
114 | Instead of granting access rights on individual mail folders to individual | |
115 | accounts, the access rights can be granted to an access group | |
b0322a85 | 116 | <span class="quote">“<span class="quote">name</span>”</span>, and all members of this group get the specified access |
d9898ee8 | 117 | rights.</p><p> |
b0322a85 | 118 | The access group name <span class="quote">“<span class="quote">administrators</span>”</span> is a reserved group. |
d9898ee8 | 119 | All accounts in the <code class="literal">administrators</code> group automatically |
120 | receive all rights to all accessible folders.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> | |
121 | This option may be specified multiple times to specify that the account | |
122 | belongs to multiple account groups.</p></div></dd><dt><span class="term"><code class="literal">sharedgroup=</code><em class="replaceable"><code>name</code></em></span></dt><dd><p> | |
b0322a85 | 123 | Another option used by Courier-IMAP. |
d9898ee8 | 124 | Append "name" to the name of the top level virtual shared folder |
125 | index file. This setting restricts which virtual shared folders this | |
126 | account could possibly access (and that's on top of whatever else the | |
127 | access control lists say). See the virtual shared folder documentation | |
128 | for more information.</p><p> | |
129 | For technical reasons, group names may not include comma, tab, "/" or "|" | |
d50284c4 | 130 | characters.</p></dd></dl></div></div></div><div class="refsect1"><a id="idm255224373824" shape="rect"> </a><h2>SEE ALSO</h2><p> |
