@@ -210,6 +210,103 @@ but membership no longer checks directory recreation during login. Preserve the
 connector mapping for other services; migrating Dex to immutable user IDs is a
 separate coordinated change, not an automatic part of this release.
 
+### Self-service account profile
+
+Signed-in members can choose **Edit profile** from their membership page.
+Deploy the new membership image, apply migration `0005_profile_email_change`,
+and deploy the updated static CSS/proxy configuration. No new public settings
+or credentials are required. Login remains Dex-only: the profile editor reads
+LDAP **only when opened**, because the configured Dex LDAP connector exposes
+username/email/name/groups, not arbitrary LDAP attributes. Cached OIDC claims
+are neither a complete nor a current editable profile. Do not map the gamer tag
+to `preferred_username` or change `idAttr` to expose it.
+
+| Profile label | LDAP attribute |
+| --- | --- |
+| About you | `description` |
+| Gamer tag (one value) | `displayName` |
+| Email address (verified separately) | `mail` |
+| First name / Last name | `givenName` / `sn` |
+| Profile photo | `jpegPhoto` |
+| City/town / State/province | `l` / `st` |
+| Websites | `labeledURI` |
+| Mobile numbers / Phone numbers | `mobile` / `telephoneNumber` |
+| Organizations / Job titles | `o` / `title` |
+| Postal addresses / Postal codes | `postalAddress` / `postalCode` |
+| Street addresses / Room numbers | `street` / `roomNumber` |
+| SSH public keys | `sshPublicKey` |
+| Password | RFC 3062 Password Modify (never read back) |
+
+The form preserves existing multi-value attributes. Enter one value per line;
+separate multiline postal addresses with a blank line. Blank optional fields
+are removed on save; `sn` remains required by the directory schema. JPEGs are
+limited to 1 MiB and 4096 pixels per side/16 million pixels, resized to fit 512
+pixels and reencoded without metadata. Existing photos are sanitized again
+before private, authenticated delivery. No arbitrary URLs are fetched. Supported
+SSH keys are Ed25519, RSA >=2048 bits and ECDSA NIST P-256/P-384/P-521; private
+keys, authorized_keys options and malformed values are rejected.
+
+**Directory prerequisites:**
+
+- The service account needs read/search access to the profile attributes above,
+	plus `uid`, `entryUUID`, `objectClass` and `modifyTimestamp`, across the
+	intended account search tree. It never needs read access to `userPassword`.
+	Accounts are pinned to immutable UUIDs; missing/deleted entries do not fall
+	back to a reused username. LDAP unavailability disables editing rather than
+	presenting an empty form that could erase values.
+- Every write binds with the member's **current LDAP password** and checks that
+	entry's UUID again. Configure directory **self-write ACLs** only for these
+	profile attributes and self Password Modify; do not grant writes to `uid`,
+	`entryUUID`, account DNs, POSIX IDs, group membership or administrative fields.
+	This supports existing Dex users outside the website registration OU without
+	granting the membership service unrestricted directory write permissions.
+- Install the `ldapPublicKey` auxiliary schema before SSH editing. When a user
+	supplies keys and the class is absent, the application adds **only** the fixed
+	`ldapPublicKey` class in the same modify. Either pre-add that class to editable
+	accounts or permit precisely that self-add with value-scoped `objectClass`
+	ACLs. Never grant arbitrary self-write to `objectClass`. No schema/ACL changes
+	are automatically applied by the website or OpenLDAP role.
+- OpenLDAP must support critical RFC 4528 assertion controls. Profile/email
+	writes assert UUID and last-modified time, and profile forms carry a signed,
+	one-hour revision to reject stale edits. A server rejecting the critical
+	control must fail closed; do not silently retry without it.
+- Maintain directory-side unique `mail` and `uid` enforcement across all
+	registrars. A client-side email preflight cannot prevent concurrent claims
+	and may be restricted by self-read ACLs; the server uniqueness overlay is
+	required. Review which services use `mail` as an account/recovery identifier.
+
+Email is changed separately: the user enters their current password, receives
+a one-hour verification link at the new mailbox, then signs into the same local
+account and enters their password again. GET/scanner visits never modify LDAP.
+Tokens are stored only as hashes, bound to account/LDAP UUID, and consumed once.
+Confirming replaces **all existing mail values** with the verified address and
+updates the local contact address; it does not attach another user's billing
+history. Old Dex/downstream tokens may retain the prior email until refreshed.
+
+Password changes send current/new passwords through Password Modify as the
+authenticated user, never a service-account reset or direct `userPassword`
+write. **Hashing remains OpenLDAP's policy**: no MD5-Crypt hash is generated by
+the application, no stored hash is exposed, and the application does not force
+or silently change the server's scheme. A legacy MD5-Crypt directory can still
+verify current passwords; do not introduce MD5-Crypt as a new application-side
+hashing scheme. Audit/migrate weak server hashing separately. The existing
+Argon2 gate for new registration remains unchanged. Password changes sign out
+the current membership browser; other membership/Dex/service sessions are not
+automatically revoked—use each service's session controls when necessary.
+
+All writes are CSRF-protected and rate-limited per account/IP. Passwords and
+profile form bodies must never be logged by ingress/APM/LDAP debug logging.
+Profile data can be shared by directory-consuming services: the page is private,
+but it does not make phone/address/SSH fields private in the directory. Enforce
+directory read ACLs and tell users what other services can access. TLS defaults
+are unchanged; the existing explicit plaintext opt-in also exposes profile
+passwords/data and should not be used on untrusted networks.
+
+The supplied Kubernetes ingress accepts up to 2 MiB; Apache allows that limit
+only under `/members/profile/` and retains 256 KiB for other member routes.
+Mirror the limits at any additional edge proxy. Oversized or invalid uploads
+must be rejected before reaching image processing.
