Steps to Reproduce:
Hide

1) start server with standalone-elytron.xml
2) use following CLI commands for setting LDAP authentication for application

/subsystem=elytron/dir-context=local-ldap:add(url="ldap://127.0.0.1:10389",principal="uid=admin,ou=system",credential="secret") /subsystem=elytron/ldap-realm=ldap-auth:add(dir-context=local-ldap,identity-mapping={rdn-identifier=uid,search-base-dn="ou=People,dc=jboss,dc=org",user-password-mapper={from="userPassword",writable=true,verifiable=true},attribute-mapping=[{from=cn,to=myRole,filter="(member={0})",filter-base-dn="ou=Roles,dc=jboss,dc=org"}]}) /subsystem=elytron/simple-role-decoder=myRole-to-role:add(attribute=myRole) /subsystem=elytron/security-domain=LdapAuth:add(default-realm=ldap-auth,permission-mapper=login-permission-mapper,role-mapper=combined-role-mapper,realms=[{realm=ldap-auth,role-decoder=myRole-to-role}]) /subsystem=elytron/http-authentication-factory=ldap-http-authentication:add(http-server-mechanism-factory=global,security-domain=LdapAuth,mechanism-configurations=[{mechanism-name=BASIC,mechanism-realm-configurations=[{realm-name="Ldap Realm"}]}]) /subsystem=undertow/application-security-domain=ldap:add(http-authentication-factory=ldap-http-authentication)

3) start LDAP server (it must be same server as was added to dir-context) with following ldif:

dn: ou=People,dc=jboss,dc=org objectclass: top objectclass: organizationalUnit ou: People dn: uid=jduke,ou=People,dc=jboss,dc=org objectclass: top objectclass: person objectclass: inetOrgPerson uid: jduke cn: Java Duke sn: Duke userPassword: Password dn: ou=Roles,dc=jboss,dc=org objectclass: top objectclass: organizationalUnit ou: Roles dn: cn=JBossAdmin,ou=Roles,dc=jboss,dc=org objectclass: top objectclass: groupOfNames cn: JBossAdmin member: uid=jduke,ou=People,dc=jboss,dc=org description: the JBossAdmin group

4) deploy testing application print-roles.war (see Jira attachments) -> deployment succeed (optionally you can try to login to http://127.0.0.1:8080/print-roles/protected/printRoles?role=JBossAdmin, use jduke/Password credentials)
5) stop LDAP server
6) reload server -> exception is thrown to server log and deployment failed

In case when LDAP server used by Elytron dir-context is unreachable (e.g. LDAP is down or some network failures occur) or when dir-context is incorrectly set (e.g. used password is wrong) then application which uses this dir-context cannot be deployed. Deployment fails and confusing exception occurs in server log.

We request blocker since it causes that deployments (which have already been successfully deployed) can unexpectedly fail when server is restarted/reloaded in time when LDAP server is unreachable.

Deployment fails with following exception in server log:
